Dr. Seibyl co-founded IND with Dr. Marek in 2001 and has provided scientific leadership since IND’s founding. Prior to IND, Dr. Seibyl was Chief, Section of Nuclear Medicine and Associate Professor of Diagnostic Radiology and Psychiatry, Yale University School of Medicine. He received his undergraduate degree at Yale College and completed his medical degree at Case-Western Reserve University in Cleveland, Ohio. Dr. Seibyl trained as a post-doctoral fellow in the Department of Psychiatry at Yale University where he won the Seymour Lustman Research Prize in the Department of Psychiatry two consecutive years. He joined the faculty as an Assistant Professor upon completion of this training. While on the psychiatry faculty Dr. Seibyl's interest in brain imaging led to his returning for a training Fellowship in Nuclear Medicine at Yale under Dr. Paul Hoffer. He was recruited to the Diagnostic Radiology faculty and was appointed the Director of the NeuroSPECT Center, a clinical brain imaging research lab in the Section of Nuclear Medicine. Dr. Seibyl subsequently became Chief of the Section of Nuclear Medicine and Director of the Yale/VA PET Center. Dr. Seibyl has won numerous grants and contracts in the context of his work in brain imaging. He serves on the editorial board of the European Journal of Nuclear Medicine and is a frequent reviewer for top-tier nuclear imaging journals. He serves on international panels for his work in neurodegenerative disease imaging, working closely with Dr. Marek to establish the NeuroSPECT Center as the premier Parkinson disease brain imaging research center in the world. Recent projects include the development of a web-based normal brain image database, and on-going work applying brain imaging techniques and analytic methods to improve the diagnosis and assessment of disease status in patients with neurodegenerative diseases.

David S. Russell, M.D., Ph.D. Director of Clinical Research
Dr. Russell has served as a Principal Investigator for IND since 2007.  He currently serves as Director of Clinical Research for both IND and its research partner, Invicro, LLC.  For 12 years prior to working with IND, Dr. Russell was a member of the Yale Movement Disorders Clinics, and is currently an Assistant Clinical Professor at the Yale University School of Medicine. At the IND he directs or participates in a number of clinical trials relating to neurodegenerative diseases ranging from Parkinson’s disease to Alzheimer’s disease to multiple sclerosis and others. Dr. Russell received his undergraduate training in Biology at Oberlin College and completed a Medical Scientist Training Program (M.D., Ph.D.) at Cornell University Medical College and the Sloan-Kettering Institute in New York. His internship in Internal Medicine and residency in Neurology were performed at Yale-New Haven Hospital and he was selected as Chief Resident in Neurology for 1994-1995. Over the years, he has directed a number of basic scientific studies related to dopaminergic brain function for over a decade. He has been an active participant in the Parkinson Study Group and served as an investigator in multi-site clinical trials of Parkinson’s disease.  In 2007, he expanded his role in clinical trials of neurodegenerative disorders by joining IND. Dr. Russell’s research and clinical interests include investigations of the mechanisms, detection, and potential prevention of neuronal dysfunction, as well as development of early molecular and biomarker indicators of loss or alteration of function of specific brain systems. He has published widely in important neuroscience journals and spoken at numerous national and international meetings.
