  • 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.
