Dr. Keene received his education at the University of Nevada, Las Vegas (B.S. in Cell and Molecular Biology) and at the University of Minnesota (M.D. and Ph.D. in Neuroscience). His Anatomic Pathology residency and Neuropathology fellowship were completed at the University of Washington (UW) where he earned a faculty position in Neuropathology after graduating. Dr. Keene is currently the Nancy and Buster Alvord Endowed Chair in Neuropathology, Professor of Laboratory Medicine and Pathology, Adjunct Professor of Ophthalmology and Neurological Surgery, Director of the Division of Neuropathology, and Associate Director of the UW Alzheimer’s Disease Research Center. Dr. Keene is the founding director of the Pacific Northwest Brain Donor Network and the UW BioRepository and Integrated Neuropathology (BRaIN) laboratory and leads the UW ADRC Precision Neuropathology Core.

Dr. Keene is Board Certified in Anatomic Pathology and Neuropathology and regularly attends on the UW Medicine surgical neuropathology and ophthalmic pathology services. He is the former Director and current Associate Director of the UW Neuropathology Fellowship and enjoys significant mentoring, teaching, and training opportunities. Dr. Keene strives to promote scientific advancement in human brain structure and function, aging, neurodegeneration, neurotrauma, and neurooncology through diagnostic and research neuropathology. Dr. Keene supervises a team of scientists, fellows, research coordinators, and histotechnologists who respectfully and expeditiously perform brain and other research tissue donations and studies in a manner that maximally and optimally preserves tissues for diverse applications. Dr. Keene energetically promotes tissue and data sharing, and facilitation of local and national research through collaborative and cooperative mechanisms. The goal of the BRaIN lab is to promote human neuroscience research to propel development of diagnostic, therapeutic, and preventative approaches for brain aging, injury, and disease.

Dr. Caitlin Latimer’s clinical specialty is neuropathology, which includes the clinical practice of neurosurgical, neuromuscular, ophthalmic, and autopsy subspecialties, with a particular interest in neurodegenerative disease. Dr. Latimer is also committed to research efforts focused on the role of the synapse in neurodegenerative disease with the goal of understanding the changes that occur at the earliest stages of disease and how these changes differ in individuals without neurodegenerative disease. Dr. Latimer additionally works with neuroimaging experts through the Integrated Brain Imaging Center to bridge the gap between neuroradiology and neuropathology and enhance targeted sampling through the use of neuroimaging data and techniques.

Dr. Amber Nolan is a board certified neuropathologist with clinical expertise in surgical neuropathology, neuromuscular pathology, and neurodegenerative disease. She received her medical and doctorate training at the University of Chicago (MD and PhD in Computational Neuroscience) and then performed her post graduate training at the University of California San Francisco in both Anatomic Pathology in Neuropathology. Her research program focuses on traumatic brain injury, with the goal of understanding mechanisms that lead to cognitive dysfunction and neurodegeneration through analysis of animal models and human tissue. Currently, she is investigating the selective vulnerability of inhibitory neurons after chronic injury in frontal cortical circuits.

Dr. Rhonda Mittenzwei’s research focus is head trauma and its effects, with ongoing projects studying traumatic brain injury including blast injury and chronic traumatic encephalopathy. Because there can be multiple coexistent pathologies, Dr. Mittenzwei also studies the intersection between brain injury and neurodegenerative diseases, including Alzheimer’s disease, Lewy body disease, and vascular pathology, among others..
