Dirk Keene

Dr. C. Dirk Keene received his education at the University of Nevada, Las Vegas (B.S. in Cell and Molecular Biology) and the University of Minnesota (M.D. and Ph.D. in Neuroscience). His post-graduate medical training in Anatomic Pathology and Neuropathology was at the University of Washington where he earned a faculty position in Neuropathology. Currently, Dr. Keene is the Nancy and Buster Alvord Endowed Chair in Neuropathology, Associate Professor of Pathology, Adjunct Associate Professor of Ophthalmology and Neurological Surgery, Director of the Neuropathology Division, and Leader of the Neuropathology and Targeted Molecular Testing Core at the University of Washington.

Dr. Keene is Board Certified in Anatomic Pathology and Neuropathology and regularly attends on each of the clinical neuropathology subspecialties (neurosurgical, neuromuscular, ophthalmic, and autopsy) for UW Medicine. He enjoys significant teaching and training opportunities through diverse teaching commitments, the UW Graduate School course “PATH513: Molecular Mechanisms of Neurodegeneration”, and as Director of the Neuropathology Fellowship.

Dr. Keene strives to promote scientific advancement through diagnostic and research neuropathology. Dr. Keene supervises a team of scientists, fellows, research coordinators, and histotechnologists who respectfully and expeditiously perform research autopsies in a manner that maximally and optimally preserves tissues for diverse applications for investigators around the country whilst providing accurate and timely neuropathological diagnoses according to the latest guidelines.

Dr. Keene energetically promotes tissue and data sharing, and facilitation of local and national research through collaborative and cooperative mechanisms. He strives to adapt existing and develop novel technologies to maximize the scientific utility of archived and prospectively acquired human brain tissue. The goal of the Keene Laboratory is to facilitate development of diagnostic, therapeutic, and preventative approaches for neurodegenerative disease by combining traditional and precision neuropathological strategies in human tissues with experimental approaches in model systems.


Caitlin Latimer

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.

Kim Howard has been here since the beginning. She started the NP Core lab with Dr. Sonnen and Dr. Montine in 2009, where she was the first tech to implement the new autopsy and sampling strategy. As things evolved, Kim left the autopsy service and now leads the histology lab. Kim is a graduate of the University of Washington with a B.A. in History and a B.S. in Biology. She is also a certified Histotechnologist and has her Qualification in Immunohistochemistry from the American Society for Clinical Pathology. She loves spending time with her family and animals. She loves movies, music, baking, a good cup of coffee in the morning, simple pleasures and small victories.

If Kim had to choose a career outside of science/medicine (and wanted to make money), she would be a software engineer. However, if she decided to follow her passions, she would be a baker in a Parisian patisserie or a professional organizer.

Lisa Keene

Lisa Keene joined the lab in 2008 as a research scientist, taking over as research manager the following year. After taking leave to raise her two busy kids, she returned part-time in 2014 as a research coordinator. In 2016, Lisa jumped at the opportunity to begin working full time in the autopsy program and now manages the autopsy service. She has always had great respect for our donors and their families and feels honored to help facilitate their wishes to donate. Outside of work, Lisa enjoys being with family and would be happy living in a barn with her horse and three dogs. Lisa has been fascinated by the brain since she was in 5th grade and saw a cow’s brain at the grocery store. She took it home, mapped it with flag toothpicks and brought it to the science fair.

If Lisa had to choose a career outside of science/medicine, she would be a member of the FBI’s Behavioral Science Unit.

Amanda Keen

Amanda Keen has been with the lab since March 2019 and is a lead autopsy technician and histotechnologist. Amanda earned her B.S. in general biology from the University of Washington and her histotechnologist certification from the Indiana University School of Medicine.
