Fallon2Brian A. Fallon, MD, MPH

Professor of Psychiatry
Director, Lyme and Tick-Borne Diseases Research Center
Columbia University Medical Center
Director, Center for the Study of Neuroinflammatory Disorders & Biobehavioral Medicine, New York State Psychiatric Institute
New York, NY

Brian A. Fallon, MD, MPH. Dr. Fallon is director of the Lyme & Tick-borne Diseases Research Center at Columbia University Medical Center where he leads a team focused on biomarkers, diagnostics and treatment of chronic Lyme symptoms. His team’s recent work has included the testing of novel diagnostic assays in a large community study, with the net result of the identification of a more sensitive Lyme Western blot. His team’s work on Lyme encephalopathy led to the discovery of hundreds of unique proteins present in the CSF of Lyme patients but not in the CSF of patients with chronic fatigue syndrome or healthy controls. His team’s current focus is on clarifying the immunologic profile and neural circuitry of patients with persistent symptoms. His team is also investigating the CNS metabolic effects of intravenous ceftriaxone using MR Spectroscopy to probe glutamatergic transmission. Dr. Dwork in his Center is examining the neuropathologic findings in post-mortem studies of patients with chronic Lyme symptoms. Dr. Moeller in his Center is examining the interaction between peripheral immunologic markers, central immune markers, and brain neurocircuitry among patients with chronic symptoms with the goal of identifying of biomarkers to help guide treatment recommendations.

Dr. Fallon serves on the editorial and review board of three journals, has lectured and published widely, and most recently has led an international team for the American Psychiatric Association’s revision of DSM-5 to clarify the prevalence of illness anxiety in the general population.

He has been actively involved in diagnosis and treatment of Lyme disease and related disorders since 1988. He has published articles on Lyme disease in peer-reviewed scientific journals and has presented poster abstracts and talks at national and international conferences on Lyme disease and other tick-borne diseases. He is the author of In the Crucible of Chronic Lyme Disease, a documentational history of the struggle to characterize the nature of Lyme disease in the late 20th and early 21st centuries.

He has cared for many persons seriously ill with chronic and neurologic Lyme disease. His work has focused on the serious morbidity and (occasional) mortality that can eventuate from this aspect of the illness. He has emphasized the urgent need for widespread clinical availability of improved methods of diagnostic testing and for development of improved methods of treatment for Lyme disease in all its stages. He holds the first United States patent issued proposing application of acaricide to deer for area-wide control of deer-tick populations as a means of reducing the incidence of Lyme disease.

James Occi headshotJames L. Occi, MS, MA, PhD (in progress)
Center for Vector Biology, Department of Entomology, Rutgers University, New Brunswick, NJ
Research/Teaching Specialist, Rutgers New Jersey Medical School, Newark

James (Jim) Occi is a microbiologist who has been involved in searching for new antibiotic entities for almost 30 years. He has done research in big pharma for over 20 years and continues this endeavor as a research microbiologist at New Jersey Medical School in the Department of Emerging Pathogens (Newark). Jim is pursuing his PhD at Rutgers University at the Center for Vector Biology (New Brunswick) and wants to be a medical entomologist when he grows up. For his thesis, Jim is studying tick-borne diseases in New Jersey tick populations under the direction of Dr. Dina Fonseca. He has a BS and MA in Biology from Montclair State University and an MS in Microbiology from Seton Hall University.

He has been working on two projects at University of Medicine and Dentistry in Newark. One project involves developing an assay for small-molecule inhibitors of Mycobacterium tuberculosis within macrophages. A second project utilizes a relatively safe surrogate of Rickettsia rickettsii, R. canadensis, in the hopes of developing an assay to look for small molecular weight inhibitors of rickettsia. Recently, he was involved in a major drug discovery program using small molecule inhibitors against species of Francisella, Yersinia, Bacillus, Burkholderia, Staphylococcus, Brucella and Legionella, designed and developed an assay to detect Yersinia pestis and Y. pseudotuberculosis YOP proteins. He just enrolled in the graduate Entomology Program at Rutgers. His first project will be looking at the prevalence of rickettsia in American dog ticks in New Jersey.

Much of his experience was learned as a Research Microbiologist at Merck Research Labs where he was involved in many different drug-discovery programs in the search for new antibiotics. Many projects required skills in microbiology, molecular biology and biochemistry.

While at Merck he was instrumental in bringing a promising thiazol-peptide antibacterial compound to pre-clinical status. Involved in strain development of the producing organism as well as determining mechanism of resistance in Staphylococcus aureus. He also developed an assay that led to the discovery novel thiazol-peptide antibacterials, and assisted natural product chemists in identifying novel structures.

His expertise in tick-borne diseases began as a MS thesis where he was involved in collecting and indentifying ticks and analyzing them for infectious agents by PCR and fluorescent antibody. As an offshoot of this work, he developed a seminar for the lay public as well as health-care professionals and lectured extensively throughout the state for years.  He has consulted for many groups and is on the scientific advisory board for the Lyme Disease Association.
