Dr. Juan Troncoso is a professor of pathology and neurology at the Johns Hopkins University School of Medicine. He is a board-certified neurologist and neuropathologist with expertise in the pathological diagnosis of dementias and the neuropathology of normal aging.
Dr. Troncoso serves as the director of the Brain Resource Center and leads the Neuropathology Core of the Alzheimer's Disease Research Center and Parkinson's disease Center at the Johns Hopkins University.
He earned his M.D. from the Pontificia Universidad Católica de Chile. He completed a residency in neurology at Hahnemann Medical College in Philadelphia followed by a Fellowship in neuropathology at the Johns Hopkins School of Medicine. He joined the Hopkins faculty in 1983.
Dr. Troncoso's research interests include the neuropathology of normal aging and its intersection with neurodegenerative diseases. The approach of Dr. Troncoso and his laboratory is to conduct morphological studies relevant to the pathobiology of aging and age-associated dementias and movement disorders, and concurrently to collaborate with studies of genetics, molecular biology, and proteomics of these disorders. Dr. Troncoso and his collaborators have been leaders in the application of unbiased stereology to the investigation of neurodegenerations and normal aging. The research activity of Dr. Troncoso is reflected in more than 350 peer-reviewed publications.
In the teaching domain, Dr. Troncoso has been director of the Johns Hopkins neuropathology Fellowship program for more than 20 years. In this capacity, he has supervised the training of many generations of neuropathologists. He is a faculty member of the Aging and Dementia Training Program and of the Pathobiology Graduate Program at Johns Hopkins.
In parallel to his service and academic activities at Johns Hopkins, Dr. Troncoso has served as neuropathology consultant for the Office of the Chief Medical Examiner of Maryland since 1981. This experience in forensic neuropathology is the basis for his book Essential Forensic Neuropathology. (Lippincott, Williams & Wilkins 2009).
