Timothy J. Collier

Dr. Timothy J. Collier is a Professor of Translational Neuroscience at Michigan State University College of Human Medicine, where he serves as Director of the Michigan State University Udall Center of Excellence in Parkinson's Disease Research. He holds dual appointments in the MSU Neuroscience Program and MSU BioMolecular Science Gateway Faculty, with his laboratory based at the Grand Rapids Research Center.

Dr. Collier received his undergraduate training in psychology at the University of Minnesota (B.A., 1974) and completed his graduate studies in psychology and neuroscience at Northwestern University (M.S., 1979; Ph.D., 1983). He conducted postdoctoral training at the University of Rochester with Dr. John Sladek Jr., focusing on cell transplantation in animal models of Parkinson's disease and aging.

His research program investigates the fundamental relationship between aging and neurodegenerative diseases, particularly Parkinson's disease. Dr. Collier's laboratory employs a range of models from primary cell culture to nonhuman primates, with current projects examining cellular senescence mechanisms, progerin and klotho gene effects on neurodegeneration, and repurposing existing drugs for Parkinson's treatment. His work bridges basic neuroscience with translational applications, emphasizing how aging serves as an active driver rather than merely a risk factor for neurodegenerative conditions.

Analysis of Dr. Collier's recent publications reveals a strong interdisciplinary focus spanning neuroscience, cardiology methodology, and statistical approaches to clinical research. His work demonstrates consistent contributions to understanding Parkinson's disease mechanisms while also advancing methodological approaches in clinical trial design, particularly in cardiology. The integration of aging biology with neurodegenerative disease processes represents a distinctive hallmark of his research program.

Dr. Collier maintains active collaborations across multiple research groups studying Parkinson's disease, including the Counts Lab, Gordon Lab, Kanaan Lab, Lipton Lab, Morgan Lab, Sammi Lab, Sortwell Lab, Steece-Collier Lab, and Vega Lab at Michigan State University.

His technical expertise encompasses primary neuronal cultures, stereotaxic surgery, immunohistochemistry, brain tissue microdissection, behavioral evaluations of motor performance in rodents, and stereology. These methodologies support his laboratory's investigation of both fundamental mechanisms of neurodegeneration and potential therapeutic interventions.
