Dr. Fallon’s research has focused on neuropsychiatry — the discipline that studies the behavioral and mood effects of diseases that affect the brain. His particular areas of research focus in Lyme disease include phenomenology, diagnostics, neuroimaging, biomarker, and treatment studies. Dr Fallon has lectured on Lyme disease nationally and internationally and was the lead investigator of one of the NIH-funded U.S. Clinical Trials of Post-treatment Lyme disease. Dr. Fallon has published over 100 peer-reviewed articles, review papers, and book chapters and he has served as a reviewer for many journals, including JAMA, Journal of Infectious Disease, Clinical Infectious Disease, and the American Journal of Psychiatry.

  • Shannon Delaney, MD

    Director, Child and Adolescent Research and Evaluation at the Lyme & Tick-Borne Diseases Research Center

    Dr. Delaney is a neuropsychiatrist at Columbia University Irving Medical Center who is co-investigator with Dr. Fallon on studies of adults and children with Lyme disease. She completed her NIH-sponsored research fellowship at Columbia University in 2017. Her clinical research has focused on immune and infectious contributions to psychiatric disease, especially psychosis in children and young adults. A member of our team for over three years, she has recently joined an initiative to establish a PANDAS/PANS clinical assessment, treatment, and research center with experts from the Columbia Departments of Neurology, Pathology, and Psychiatry. This PANS/PANDAS initiative will allow children and young adults with complex neuropsychiatric presentations to be evaluated for a variety of infectious and immune causes of neuropsychiatric disorders.

  • Carolyn Britton, MD

    Associate Professor of Neurology at Columbia University Irving Medical Center

    Dr. Britton is an associate attending physician at NewYork-Presbyterian Hospital. Dr. Britton led the neurologic component of the NINDS-Funded study of Post-Treatment Lyme Encephalopathy and is co-author on many related papers. She also is the current president-elect of the Board of Trustees of the National Medical Association, where she is involved in the association’s Health Literacy and Cultural Competency campaigns and training programs. Dr. Britton received an MD from New York University, where she also received an MS in Microbiology (Virology). She completed her internship and residency in internal medicine at Harlem Hospital Center, Columbia University affiliation, followed by a residency in neurology and a research fellowship in neurovirology at the Neurological Institute. Dr. Britton is a recognized expert in neurovirology and infectious/inflammatory diseases of the nervous system. For more than 20 years, she has worked tirelessly to support funding for AIDS clinical trials, the training of minority and women clinical researchers, and the inclusion of minority populations and women in clinical trials. She has held leadership positions in several professional organizations and boards, including Board of Trustees NMA, American Academy of Neurology, the Governor’s Task Force on AIDS (New York), and the Manhattan Central Medical Society.

  • John G. Keilp, PhD

    Neuropsychologist and Associate Professor at Columbia University Irving Medical Center

    Dr. Keilp is a consulting neuropsychologist in the Lyme and Tick-Borne Diseases Research Center and head of the Neuropsychology Laboratory in the Division of Molecular Imaging and Neuropathology (MIND) at the New York State Psychiatric Institute. He has extensive experience in the assessment of cognitive impairment in psychiatric (depression, bipolar disorder, schizophrenia), neurologic (dementia), and infectious (Lyme disease and HIV) diseases. He has conducted numerous studies examining correlations between cognitive deficits and various biological measures. Dr. Keilp has extensive experience with neuropsychological assessment in the post-treatment Lyme disease syndrome, and is widely published in peer-reviewed journals.

  • Andrew J. Dwork, MD

    Professor of Clinical Pathology and Cell Biology in Psychiatry

    Andrew Dwork, MD, has a broad range of expertise in neuropathology, having conducted research on hippocampal neurogenesis, the blood brain barrier, and neural epigenetic regulation. Dr. Dwork and his colleague Gorazd Rosoklija, MD, PhD (neurologist and neuropathologist) oversee the post-mortem repository of brain and spinal-cord specimens which contains specimens from generous patients with a history of Lyme disease. Dr Dwork is co-investigator with Dr. Fallon, Dr. Monica Embers, and Dr. Tim Sellati on a post-mortem study of human Lyme disease. Using bright field double immunohistochemical labeling techniques, Dr. Dwork and Dr. Rosoklija examine the post-mortem brains for evidence of microglial activation, macrophages, and altered blood-brain barreir. Next these post-mortem tissues are probed for Borrelia spirochetes and other microbes by our collaborating co-investigators.

  • James R. Moeller, PhD

    Research Scientist at Columbia University Irving Medical Center

    Dr. Moeller is a Research Scientist/Assistant Professor in the Neuroinflammatory and Somatic Disorders Center and the Lyme and Tick-borne Diseases Research Center. He has pioneered the development of novel analytic techniques to identify brain networks that are applicable to both brain activation data and neural fiber-track data. He has published and lectured widely on the use of his methods in both the clinical and behavioral neurosciences. He has made substantive contributions to clinical research on age-related diseases, including late-life depression and Parkinson's and Alzheimer’s neurodegenerative diseases; and genetic neurodegenerative disorders, including Huntington's and Torsion dystonia. Dr. Moeller also continues to contribute to the research on the brain’s role in successful aging in the elderly. Lastly, his most recent investigations of the brain-body-health relationships that underlie Lyme disease and related post-treatment syndromes mirrors his much earlier interest and involvement in research on infectious neurological diseases like HIV dementia.

  • Alla Landa, PhD

    Director, Pain Research in the Center for Neuroinflammatory and Somatic Disorders

    Alla Landa, PhD, is an Assistant Professor of Clinical Psychology in Psychiatry at Columbia University, and a Research Scientist in the Center for Neuroinflammatory and Somatic Disorders and the Lyme and Tick-Borne Diseases Research Center. Her NIH-funded research bridges clinical psychology and developmental neuroscience and aims at clarifying the pathophysiology of somatic symptoms (e.g. chronic pain) and developing effective treatments. Dr. Landa is currently principal investigator of a fMRI study of chronic pain among patients previously treated with antibiotics for Lyme disease.
