John Quinn Trojanowski (December 17, 1946 – February 8, 2022) was an American academic research neuroscientist specializing in neurodegeneration.
[3] Trojanowski held major leadership positions at the University of Pennsylvania including: Director of a National Institute of Aging (NIA) Alzheimer's Disease Center (1991–2022), Principal Investigator of a NIA Program Project Grant on Alzheimer's (AD) and Parkinson's (PD) disease (1990–2005), Director of Medical Pathology (1988–2002), Interim Director (2001–2002) and Director (2002–2022) of the Institute on Aging, Co-Director (1992–2022) of the Center for Neurodegenerative Disease Research, Director, National Institute of Neurological Disorders and Stroke (NINDS) Morris K. Udall Parkinson's Disease Research Center of Excellence (2007–2022), the first William Maul Measey–Truman G. Schnabel, Jr., M.D., Professor of Geriatric Medicine and Gerontology (2003–2022) and Co-director of the Marian S. Ware Alzheimer Drug Discovery Program (2004–2022).
[3] For more than fifteen years, Trojanowski conducted research on AD, PD, motor neuron disease, dementia with Lewy bodies (DLB), frontotemporal lobar degeneration (FTLD) and other aging related nervous system disorders.
The major goal of his research was to translate advances into understanding mechanisms of aging related neurodegenerative diseases into meaningful interventions to treat or prevent these disorders.
[3] Trojanowski died in Philadelphia from complications of chronic spinal cord injuries on February 8, 2022, at the age of 75.
