John H. Wahlert, Ph.D., Harvard University (Vertebrate Paleontology), is a paleontologist who investigates the interrelationships of rodents based chiefly on cranial anatomy. His articles are published in American Museum Novitates and elsewhere. Research is carried out in the Mammalogy and the Vertebrate Paleontology Departments at the American Museum of Natural History.
Dr. Wahlert has arranged for students to conduct honors research there under his direction at the Museum. Dr. Wahlert served for six years as Chair of the Natural Sciences Department and for three years as Chair of the School of Liberal Arts and Sciences Personnel and Budget Committee.
Professor Wahlert is a member of the CUNY Graduate Faculty in Biology—specialization in Ecology, Evolutionary Biology and Behavior (EEB). He teaches a graduate course on Mammalogy and compiled a bibliography of classic works on mammals, which is available on the Museum of Natural History web site. He is also a Resource Faculty member of the New York Consortium in Evolutionary Primatology.
“My research investigation into the relationships of living and extinct rodents began when I was an undergraduate at Amherst College and wrote an Honors Thesis on the microstructure of incisor enamel in fossil rodents. I shifted my focus to the examination of cranial foramina (holes in the skull) for my Ph.D. thesis. My most influential publication was a portion of my dissertation published by the Museum of Comparative Zoology, Harvard University, in 1974. In this paper, I built on the work of others to establish a nomenclature for the description of cranial foramina in the most primitive rodents. The latest publication in this series concerns the ear bone of an early fossil rodent from North America.”
On a humorous note, an extinct beaver, Palaeocastor wahlerti, was recently described and named by Dr. William Korth.

New anatomical structures evolve through modifications to development. Dr. Calamari’s research focuses on the way development, as well as accompanying changes in gene expression during development, are responsible for the evolution of complex anatomical structures. He integrates diverse lines of evidence, such as 3D geometric morphometrics and high-throughput transcriptomics (sequencing all the genes expressed in a given tissue at a given point in time), to answer these questions, with a focus on the evolution of cranial appendages (horns, antlers, and other bony outgrowths) of even-toed, hoofed mammals (artiodactyls). Dr. Calamari’s research interests also include inferring evolutionary trees and using comparative tree-based statistics to understand morphological and genomic evolution. He has studied a broad diversity of mammals, from bank voles to mammoths and mastodons, and is interested in mentoring student research that leverages high throughput sequencing data as well as the excellent collections at the American Museum of Natural History.

Originally from New Jersey, Dr. Dobi did her graduate work at Harvard University, where she studied transcriptional regulation in yeast. After receiving her Ph.D. in Genetics in 2007, she spent several years as a postdoctoral fellow at Memorial Sloan Kettering Cancer Center in New York City, where she was the recipient of a NIH/Ruth L. Kirschstein postdoctoral fellowship to study transcriptional regulation of muscle development in Drosophila melanogaster. Her work as a postdoc uncovered new roles for a dozen transcription factors in fruit fly muscle development.
Dr. Dobi’s current research focuses on the formation of unique muscles during fruit fly embryonic development. In particular, she is interested in how muscles with distinct sizes, shapes, attachments and innervations are formed by the interplay of different transcription factors during development. She uses molecular, cellular and genetic approaches to understand basic questions of cellular specification.
There are opportunities for students to join the research in the Dobi Lab; please contact Dr. Dobi for more information.

I was born and raised in New York City, but decided to travel away from home for my education. I received my B.A. in Biology from Grinnell College in Iowa. As a college student I was first exposed to laboratory research and found that I enjoyed the hands-on aspect of doing science. I decided to continue my science education and went to the University of Wisconsin-Madison for graduate school, where I earned a PhD in Cellular and Molecular Biology.
Upon returning from the Midwest, I spent several years as a Research Fellow at Albert Einstein College of Medicine in the Bronx. At Einstein I began to study the biology of melanized fungi, the subject of my current research.
My research interests focus on fundamental questions in the biology of melanotic fungi. Melanins are a family of related compounds that have remarkable physical properties. They are found throughout the natural world and have diverse functions ranging from camouflage and display, to protection from ultraviolet radiation and enhancement of virulence in microbes.
Melanins are found in many fungi, including known pathogens, and play important roles in both pathogenesis and environmental survival. I study melanization in Cryptococcus neoformans, a fungal pathogen that is a relatively frequent cause of disease in immunocompromised individuals.

Pablo Peixoto is an Assistant Professor of Natural Sciences. He completed his PhD studies in Cell Biophysics at the University of Extremadura, Spain in 2006. His research provided the first plausible explanation of how mitochondria import proteins from the cell cytoplasm without compromising the permeability barrier that is essential for energy production. In 2007, Professor Peixoto moved to New York University to study therapeutic approaches for control of cell death. He was awarded the “Young Bioenergeticist Award” from the Biophysical Society in 2010. The following year he moved to the Weill Cornell Medical College, where he studied the role of mitochondria in neurodegenerative diseases that assail the aging human population. His current research at Baruch College pertains to understanding how mitochondria interact with the rest of the cell in health and disease contexts.

Valerie Schawaroch received her Ph.D. in October 2000 from The Graduate School and University Center of the City University of New York (Biology: ecology, evolution and behavior). She subsequently served as a co-principal investigator on a National Science Foundation funded research project conducted at the American Museum of Natural History.
“I study the evolutionary history of fruit flies in the family Drosophilidae. My research employs both molecular and morphological techniques to identify species and determine relationships among these species. Molecular techniques employed are DNA isolation, PCR amplification (to make copies of trace amounts of DNA) and DNA sequencing (to read the genetic code of the fly species). The morphology or external features of these tiny flies are examined with traditional light microscopes as well as the scanning electron microscope and the confocal laser scanning microscope. My current collaborations are with researchers at the American Museum of Natural History, The City College of New York and The Newark Museum.”

Rebecca Spokony joins Baruch as Assistant Professor of Natural Sciences. Her lab focuses on hormonal regulation of development, which she started examining at the University of Arizona during her Ph.D. work on central nervous system reorganization during metamorphosis of Drosophila melanogaster. She continued examining the genome-wide targets of the two main hormones involved in metamorphosis, ecdysone and juvenile hormone during postdoctoral work at the University of Chicago. Professor Spokony was a member of the ModENCODE consortium, producing publicly available reagents and transcription factor DNA-binding data for ~125 factors. Her current research involves following-up with genetic studies of new regulators and targets involved in these hormonal pathways. She is studying how organisms integrate environmental conditions such as nutrition and circadian rhythm to produce appropriate developmental outcomes.
Dr. Bengston is a behavioral ecologist and evolutionary biologist, generally interested in how repeatable behavioral variation between individuals, colonies, populations and species affect evolutionary processes. She is particularly interested in the evolution of new life-history strategies and ecological speciation. Prior to joining the faculty at Baruch, she was a Huxley Faculty Fellow (2017-2018) at Rice University in Houston, TX and a NSF Postdoctoral Fellow (2015-2017) in the lab of Christian Rabeling at the University of Rochester (now at Arizona State University). She received her PhD in Ecology & Evolutionary Biology and Entomology from the University of Arizona (2010-2015) under the guidance of Anna Dornhaus. She earned her BcS in EEB from the University of Tennessee where she was also a member of Susan Riechert’s lab.
A native of South Carolina, Stephen completed his undergraduate degree in Biological Sciences at Clemson University before continuing on to degrees in Statistics (MA) and Ecology, Evolution, and Marine Biology (MA, PhD) at the University of California, Santa Barbara. After completing postdoctoral positions at the UCSB Marine Science Institute and the Florida State University Coastal and Marine Laboratory, he joined Baruch College and the CUNY Graduate Faculty in Biology (Ecology, Evolutionary Biology, and Behavior subprogram) as an assistant professor in 2014.
Stephen’s work focuses on understanding the mechanisms that drive patterns in diversity (including impacts of human activities), how diversity impacts ecosystem functioning and ecosystem services, and how ecology can inform, motivate, and learn from management actions. In order to consider these issues across multiple scales, his lab employs and connects field, lab, and quantitative techniques in various communities. Most of the lab’s field projects focus on understanding, restoring, and conserving coastal and aquatic communities in the Hudson River watershed (e.g., oyster reefs, salt marshes, tidal marshes, rivers), while computational work explore diversity patterns and impacts using big-data (focal areas include kelp and rain forests) and model development. He is also interested in communicating research findings to stakeholders and finding ways to connect education and research.
There are openings for new students (undergraduate and graduate) in the lab who share similar interests. Interested students should contact Dr. Gosnell at email@example.com; you can also find more information at http://www.gosnelllab.com/
David Gruber is Presidential Professor of Biology and Environmental Sciences at Baruch College, City University of New York and serves on the faculty of the Ph.D. Program in Biology at the CUNY Graduate Center and the CUNY Macaulay Honors College. He is also an Explorer for National Geographic, a Research Associate in Invertebrate Zoology at the American Museum of Natural History and an Adjunct Faculty member at the John B. Pierce Laboratory of the Yale School of Medicine.
His interdisciplinary research pertains to marine biology, genomics/transcriptomics of uncharacterized marine organism, deep-sea ecology, photosynthesis, biofluorescence and bioluminescence. He completed a PhD in biological oceanography from the Rutgers University Institute of Marine and Coastal Sciences and served as a postdoctoral fellow at the Brown University Division of Biology and Medicine, working to develop fluorescent proteins into modulatable probes with neurobiological and medical applications.
Prof. Gruber’s deep-diving scientific diving teams have discovered scores of unique biofluorescent compounds, several of which have been developed into tools to find better cancer drugs. A former tropical forester for the Smithsonian Tropical Research Institute, Gruber’s research utilizes Remote Operated Vehicles, extended-range SCUBA and soft robotics (in collaboration with the Harvard Microrobotics Laboratory) to investigate corals, sponges and delicate forms of marine fauna. Gruber is passionate about utilizing modern technology to view the underwater world from marine creatures’ perspectives. In this vein, his group developed a “shark-eye” camera to gain a shark’s perspective of their marine environment. Gruber also led the first study to apply advanced deep machine learning techniques to better detect and classify Sperm Whale bioacoustics. He is currently working on sea turtle biology, following his discovery of biofluorescence in the hawksbill sea turtle (Eretmochelys imbricata).
In addition, Prof. Gruber is committed to communicating science to the general public. He serves as a scientific advisor and producer for WNYC Studio 360’s “Science and Creativity” series and his writings have appeared in The New Yorker, The New York Times, Nature Medicine and The Best American Science Writing. He is the co-author of “Aglow in the Dark: The Revolutionary Science of Biofluorescence” (Harvard University Press). He holds master’s degrees in coastal environmental management from Duke University and in journalism from Columbia University.
From 2017-2018, David was a Fellow at the Radcliffe Institute for Advanced Study at Harvard University. Gruber was awarded the 2019 Lagrange Prize, the greatest international recognition for complex systems science, for his research “focused on the conservation of biodiversity, protection of resources and the safeguarding of ecosystems.”
My general interests are in shellfish biology, aquaculture, and marine ecology. My research has primarily focused on bivalve aquaculture and restoration. I study the physiological ecology of bivalves in order to address issues hindering the success of bivalve restoration efforts as well as bottlenecks in the aquaculture industry. An issue that I have worked on extensively is the over-winter mortality of juvenile hard clams.
I collaborate with Brooklyn College’s Aquatic Research and Environmental Assessment Center (AREAC) on a number of research programs including the early growth of horseshoe crabs and urban aquaculture.
I currently teach ‘Principles of Ecology’ (ENV_1020) and ‘Introduction to Environmental Science’ (ENV_3001). In these courses I strive for my students to understand how ecosystems work so that they have the knowledge to appreciate and protect ecological systems. I encourage undergraduate students to participate in my research as there are opportunities to do work in the field and in my laboratory at Baruch College.
Please contact me to learn more about my research and teaching activities.

Jean Gaffney completed her undergraduate degree in chemistry at Binghamton University (SUNY). She attended Yale University for her Ph.D. with Ann M. Valentine, where she studied the metal binding properties of a novel monolobal transferrin from the ascidian Ciona intestinalis. Following her doctoral work, she completed a postdoctoral fellowship at the Weizmann Institute of Science with Irit Sagi, where she focused on understanding a class of enzymes implicated in cancer known as the matrix metalloproteinases. She joined the Baruch faculty as an assistant professor in the fall of 2014.
Dr. Gaffney is interested in continuing to understand the role of the matrix metalloproteinases (MMPs) in diseases such as cancer. The MMPs have been implicated in homeostatic roles as well as in disease states, which makes them a challenging yet critical target for therapeutics.

Current Research Interests:
Research in my group focuses on thermally-activated heavy-atom tunneling (TAHAT) in organic chemistry. Thermally-activated heavy-atom tunneling is a process in which atom tunneling through the barrier may contribute to reaction rates. Determining levels of contributions of TAHAT (whether high or low) is key to understanding mechanistic details in organic reactions. My research provides a manageable route to assessing TAHAT by using computational methods. The mechanistic details that we study include reaction rates and kinetic isotope effects. The computations focus on reactions forming new carbon-carbon bonds. We computationally assess TAHAT, including potential “sweet spots” in mid and upper barrier regions to provide needed insight to mechanistic organic chemistry. My research is also being incorporated into the undergraduate organic curriculum at Baruch College. I also carry out outreach educational talks at local elementary schools with chemical demonstrations and experiments to convey the importance of fundamental science to the youngest generations of students.

My research interests can be broadly divided into two categories: Bio-inorganic chemistry & Environmental chemistry.
Bio-inorganic chemistry – I am interested in looking at the thermodynamic and kinetic aspects of transition metal complexes which are formed with macrocyclic ligands and explore their functions, properties and structure-activity relationships in biological systems. I am particularly interested in understanding the aspects of “macrocylic effect” of these metal complexes.
Environmental chemistry – I am also interested in exploring the field of pesticides and their effects on the environment. This relates to the analysis of pesticide residues on fruits, vegetables and other commodities as well as the effects of these residues on bodies of water.

Postdoctoral work, Cornell University
I began my career as an R&D chemist in the pharma industry, working on new methods for the synthesis of drug candidates. My research since coming to Baruch in 1998 started in the area of organofluorine chemistry (synthesis of halogenated anesthetic enantiomers), and currently focuses on the study of benzazepines, which are little-studied analogues of the benzodiazepine pharmaceuticals. Our group of undergraduate researchers devised one of the few general methods for obtaining these rare compounds, and is currently studying their properties with the eventual goal of testing their possible biological activity. Another facet of our research deals with indigo-like dye molecules, which are well known as components of the historical dye Tyrian Purple. Our goal is to explain the highly variable color of these dyes when they are applied to fabrics. Both of these projects involve collaboration with professors and students at Hunter College, Queensborough Community College, and Queens College.
On the administrative side, I am Deputy Chair of Chemistry, responsible for staffing the chemistry teaching schedule, and for hiring chemistry adjunct instructors. I am also Baruch’s Health Professions Advisor, and am co-chair of the Department of Natural Sciences Recommendations Committee. That Committee puts together departmental recommendations for our students applying to medical and dental schools.

Orrette was born in the coastal town of Montego Bay in northwest Jamaica. He completed his B.Sc. degree in Chemistry at Brooklyn College of the City University of New York (CUNY). After graduating, he moved to Maryland to pursue his Ph.D. in organic chemistry at the University of Maryland-Baltimore County working with Katherine Seley-Radtke. His Ph.D. work focused on the design, methodological development and the synthesis of chemotherapeutic agents possessing anticancer, antiviral and antiparasitic activities. Following his doctoral work, he joined the laboratory of Lawrence Marnett at Vanderbilt University. At Vanderbilt, his work focused on understanding the chemistry and biology of the formation of DNA adducts that are derived from lipid and/or DNA peroxidation. These adducts can then be used as means of determining their roles in mutation and carcinogenesis. He joined the Baruch faculty as an assistant professor in the fall of 2017.
Dr. Wauchope is interested in understanding the chemical biology of quorum sensing (cell-cell communication) so as to decipher the bacterial lexicon. Quorum sensing has been implicated in several deleterious processes that are hallmarks of microbial infections in the body. Consequently, work in his lab is focused on developing chemical agents that disrupt this communication mechanism as well as to investigate the processing of the chemical signals that enable cell-cell communication.

Stefan Bathe received his Ph. D. in experimental nuclear physics from the University of Muenster, Germany, in 2002. He was a postdoctoral research scientist at the University of California, Riverside, from 2003-2007. In 2008, he became a Scientific Staff Fellow of the RIKEN-BNL-Research Center at Brookhaven National Laboratory (BNL). In 2010, Prof. Bathe joined the faculty of Baruch College as an Associate Professor. From 2010 to 2015 he was jointly appointed as a Fellow of the RIKEN-BNL-Research Center at BNL. Prof. Bathe is also a faculty member of the PhD Program in physics at the CUNY Graduate Center.
Prof. Bathe’s research interest is in experimental high-energy nuclear physics. He is a member of the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) at BNL, an international collaboration of 500 scientists. The experiment studies a new phase of strongly interacting matter, dubbed the Quark-Gluon Plasma (QGP), that emerges at extremely high temperature and density. This is achieved by colliding heavy nuclei at relativistic energies and measuring the produced particles.
Prof. Bathe has worked on the measurement of neutral pions with electromagnetic calorimeters, which in 2001 led to the discovery of jet quenching in heavy ion collisions. In recent years, his group has focused on a new silicon vertex detector. The detector identifies D and B mesons through measurement of their decay vertex, providing insight into the mechanisms of energy loss of partons in the Quark-Gluon Plasma.
Prof. Bathe has taken a leading role in the experiment. He served as Physics Working Group Convenor, Run Coordinator, Analysis Coordinator, and on the Executive Council and Institutional Board.
Prof. Bathe’s research is sponsored by a grant from the Department of Energy.

Sultan Catto, Ph.D., Yale University (Mathematical Physics), has made important contributions to the development of elementary particle physics particularly in the area of dynamical supersymmetry, and in mathematics in the areas of spectral theory of automorphic forms and octonionic projective geometries with applications to quantum mechanics. He is a professor and Executive Officer for the Ph.D. Program in Physics at the CUNY Graduate School, Adjunct Associate Research Scientist in Henry Krumb School of Mines, Columbia University, and Visiting Professor at the Rockefeller University.
Professor Catto was the U.S. winner of Mathematics competitions (Math Olympiads) and spent eight months research fellowship at the University of Chicago and Argonne National Laboratory. He is also on the permanent International Advisory Board of the “International Conferences on Differential Geometric Methods in Theoretical Physics”, “International Conferences on Symmetries and Strings,” and “International Wigner Symposia”, together with internationally renowned scientists and Nobel Laureates in physics and Fields Medalists in mathematics. He has had short term physics professorships at Niels Bohr Institute in Copenhagen, Academia Sinica (Chinese Academy of Sciences) in Beijing, and Nankai University in Tianjin, China and International Center for Theoretical Physics in Trieste, Italy. He was a panel member on Hollywood and Science at International Hamptons Film Festival sponsored by the Alfred P. Sloan Foundation, and is a permanent member of the International Counsel for Development of Science and Technology in Peru. He was awarded the “Benjamin W. Lee Prize” by the International School of Sub-Nuclear Physics (Ettore Majorana) in Sicily (referees were Nobel Laureates T.D. Lee, S. Glashow and E.P. Wigner), Italy, for his work on quark-diquark supersymmetry.
Starting with a series of papers published between 1985 and the present, he and his collaborators (mainly Feza Gursey) exploited internal (dynamical) supersymmetries to construct a combined classification scheme for mesons and baryons. Theoretical models they developed led to existence of multiquark bound states which were recently grounded in experiments (for example a0 (980) and f0(975) are of this type).
More recently he is completing a book on “Algebraic Approaches to Particle Theory” with H.C. Tze of Institute for Advanced Study at Princeton and VPI. The book deals with Relativistic Quark Models, Constraint Superalgebras, Supergroups in Critical Dimensions and Lattices Generated by Discrete Jordan Algebras. Another book on “Octonionic Structures in Physics” is near its completion (with Carlos J. Moreno at Baruch and CUNY graduate school). Other problems they are currently looking at are:
1. Conformal structures in D=4; Quaternion Analyticity.
2. Euclidean Instantons from Chiral Superfields (N=2), Connections to Statistical Mechanical Models, Yang-Mills Theories.
3. Hyperbolic Extensions of Exceptional Groups and Unified Field Theories
4. Uniform Treatment of Chiral Symmetry and SU(4) Symmetry of Nuclear Forces.
5. Quaternionic and Octonionic Structures in Physics: Possible Octonionic Basis for Internal Symmetries in Nature.”
6. Multiquark states, especially recent results on pentaquarks and associated phenomenology based on split octonionic algebra approach.Close

Adrian Dumitru received his PhD in physics from the Institute for Theoretical Physics at Frankfurt University, Germany, in fall of 1997. He was a postdoctoral research scientist at Yale University from 04/1998 to 09/1999. This was followed by two postdoc positions at Columbia University in New York (1999-2001) and at Brookhaven National Laboratory on Long Island (2001-2002). From 01/2003 until 07/2008 he held a position as Assistant Professor at the ITP, Frankfurt University before joining the Department of Natural Sciences at Baruch in august 2008. Until Aug. 2013 we was simultaneously appointed Associate Professor at Baruch College and a fellow of the RIKEN/BNL research center. He is since a Professor of Physics at Baruch College
His research focuses on the physics of Quantum Chromodynamics, the theory of the strong interactions, at very high energies. The main motivation is to understand a primordial state of matter which emerges at temperatures exceeding 1012 K where ordinary hadrons melt into the fundamental constituents of matter, quarks and gluons. This new “quark-gluon plasma” state of matter existed in the early universe for about 1μsec after the Big Bang and can be recreated in the laboratory by colliding heavy ions such as lead or gold nuclei at relativistic energies.
Dr. Dumitru has worked on models for high-energy particle collisions, on effective theories for the deconfined phase of QCD in terms of Polyakov loops, on the dynamics of the chiral symmetry breaking phase transition in high-energy collisions which generates the mass of particles, and on the so-called “Color Glass Condensate” theory for the gluon distribution of hadrons and nuclei at very high energy. Recently, he has worked intensely on understanding the properties of bound states of heavy quarks and anti-quarks, such as the “bottom” quark, at high temperatures. The goal is to obtain deeper insight into one of the fundamental properties of QCD: that is, the confinement of quarks in the vacuum versus their “liberation” at high temperatures.

Ramzi Khuri received his PhD in Physics at Princeton University in 1991. He spent the past seven years as a researcher in theoretical physics. During (1991-93), he was a postdoctoral fellow at Texas A&M University. Another two years (1993-94 and 1995-96) were spent at CERN in Geneva, the leading high senergy physics research institute in the world, on a John Stuart Bell Scholarship in Quantum Physics. An additional two years (1994-95 and 1996-97) were spent as a research associate at McGill University. Most recently, he held a Particle Physics and Astronomy Research Council (PPARC) Advanced Fellowship at Queen Mary and Westfield College, University of London. This last position was at the rank of Lecturer, and was intended for five years to support unhindered research.
He resigned this position August 31st, 1998 in order to assume the tenure-track position at Baruch College. In the field of string theory, he has established an international reputation, having co-authored a review, which has now become a standard reference, and having published over 50 papers, receiving over 1,000 citations. In addition, he co-organized the conference From Superstrings to Supegravity at the Etorre Majorana Centre at Erice, Italy, in December 1992.
“My research career has concentrated mainly on the study of black holes, solitons and duality in string theory. The main motivation in this endeavour is an attempt to understand the nature of string theory as a theory of quantum gravity and uniting the four fundamental interactions of nature. Such a unified picture emerges via the introduction of duality maps, which relate seemingly different theories in various limits, and in which these theories appear as different phases of the same underlying theory. More recently, I have focused on the attempt to understand the quantum statistical-mechanical basis of the Bekenstein-Hawking (BH) black hole entropy formula from string theory and to a resolution of the Hawking radiation information paradox. The BH formula was derived recently for certain classes of black holes. I am currently engaged in trying to understand the physical basis for the success of this derivation and the correspondence between black holes and quantum-mechanical string states, a problem which lies at the heart of quantum gravity. In particular, fascinating new connections arise between black holes and certain soft-matter (polymer) systems.”

Peter Orland, Ph.D., University of California at Santa Cruz (Physics), has a record of scholarly publications that covers three different areas of particle physics, including statistical mechanics, quantum field theory(gauge theory), and string theory. He has helped postdoctoral fellowships at prestigious institutions; he spent two years at Imperial College, London, and another at Niels Bohr Institute in Copenhagen. Professor Orland has a fine record of teaching introductory physics courses for both non-majors and majors in the sciences. Dr. Orland is a faculty member of the Ph.D. Program in Physics, CUNY Graduate Center.
Currently, my main interest is the long-range physics of Yang-Mills theories, in particular QCD. I have been looking at the confinement problem in two different ways:
1. 2+1-dimensional lattice Yang-Mills theory in axial gauge. This theory admits an unusual weak-coupling expansion, different from conventional perturbation theory. The expansion is around 1+1-dimensional integrable field theories, where the spectrum and mass gap are known. Unlike the standard weak-coupling methods, confinement occurs very simply.
2. I have also been looking for some time at the properties of gauge-theory orbit space. This is the space of gauge connections modulo gauge transformations – QCD configurations are not gauge fields, but rather gauge orbits. I have been able to find the measure and Riemann curvature on this space in 2+1 dimensions on a special set of coordinates. I have been trying to find similar coordinates in 3+1 dimensions, where new obstacles occur – in some sense the Gribov problem is more severe as dimension increases.
In addition to the above I have been looking at problems in general relativity and cosmology and in integrable quantum field theories.

JOEL BRIND, PhD, graduated Yale College in 1971 and earned his doctorate from New York University in 1981 in Basic Medical Sciences, with specialization in biochemistry, physiology and immunology. Since 1986, he has been a professor of human biology and endocrinology at Baruch College of the City University of New York.
During the 1980s, he specialized in the metabolism of steroid hormones and their relation to various human diseases, including breast cancer. He pursued this research mainly with the Orentreich Foundation for the Advancement of Science, full-time from 1981-86, and part time as a consultant between 1986 and 2014.
Since coming across evidence linking abortion and breast cancer in1992, Dr. Brind has been known mostly for his research effort in studying what has come to be known as the “ABC link”, compiling and publishing critical reviews on the subject in1996, 2005 and 2018 in peer-reviewed medical journals. In 1999, Dr.Brind co-founded the nonprofit Breast Cancer Prevention Institute (of which he remains on the Board of Directors), now headquartered in Somerville, New Jersey (www.bcpinstitute.org). From 2003–2006, he served as a member of the Federal government’s CDC advisory committee on the early detection and control of breast and cervical cancer. Dr. Brind continues to analyze and conduct reviews of studies on the ABC link, as studies evidencing the link continue to emerge, mostly from China and South Asia.
Dr. Brind was also lead author of a 2015 systematic review and meta-analysis on the link between the injectable contraceptive DMPA and increased risk of acquiring HIV. Such evidence has finally (early 2017) been recognized by the World Health Organization, whose latest “Guidance statement” now stipulates: “there must be clear provision of information beforehand to enable informed decision-making” re: the use of DMPA for women at high risk of acquiring HIV.
Since 2007 Dr. Brind has also been studying amino acid metabolism in the context of nutrition and aging.
2010 he founded Natural Food Science, LLC, which makes and markets the supplement sweetamine® (www.sweetamine.com), based on his research conclusion that the amino acid glycine is the body’s most important regulator of inflammation, and that a dietary deficiency in this amino acid is largely responsible for most chronic disease (including diabetes, cancer and cardiovascular disease) rooted in chronic inflammation.

Szalda, Ph.D., Johns Hopkins University (Chemistry), is a Research Collaborator at Brookhaven National Laboratory where he uses X-ray crystallography to study the binding of carbon dioxide to metal complexes and electron transfer reactions. His publications have appeared in various journals of chemistry. He is an advisor to students in the biomedical specialization.
“The primary focus of my research is a better understanding of the basic chemical principles required to create an efficient and economical method to convert solar energy into a storable and transportable fuel. Therefore we are investigating electron transfer reactions and the binding of carbon dioxide to metal complexes in order to be able to store solar energy by converting carbon dioxide (an end product of combustion) into methane or methanol (a storable and transportable fuel). This work is done in collaboration with Drs. Norman Sutin, Carol Creutz, and Etsuko Fujitu at Brookhaven National Laboratory.”
