Professional Summary:

My professional expertise is in autopsy neuropathology, with focus on neurodegenerative disorders and forensic neuropathology, and brain banking. In the diagnostic domain, I am familiar with all major neurodegenerations to a level that allows me to teach pathology and neuropathology trainees. I gained this expertise through 20 years of examining cases from the Johns Hopkins Alzheimer’s Disease Research Center, Baltimore Longitudinal Study of Aging, Udall Center of Excellence for Parkinson’s Disease Research, Huntington Disease Center, Fronto-temporal dementia study, and BIOCARD study. My experience in forensic pathology began in 1987 at the Bureau of Forensic Medicine in Moscow, Russia, and continued thereafter with 20 years of assisting in forensic neuropathology consultations at the Office of the Chief Medical Examiner in Baltimore, Maryland.

I have 15 years of experience managing the Johns Hopkins Brain Resource Center (BRC) a repository with approximately 2500 postmortem brain specimens of neurodegenerative cases and controls. As manager of the BRC, I was responsible for dissection and preparation of tissues for research, supervised the safe storage of these valuable tissues, and provided tissue samples for research to investigators at Hopkins and extramurally. The provision of these tissues included discussions and advice to requesting investigators in terms of case selection, anatomical regions, and histological and immunohistochemical methods.

My professional experience also includes the preparation and participation in clinical pathological conferences, and the teaching of neuroanatomy and brain cutting demonstration to medical and graduate students.
