Hiroko H. Dodge, Ph.D.



Data Core Director/Associate Professor of Neurology



Dr. Dodge joined the NIA-funded Oregon Alzheimer's Disease Center (OADC) as the data core director in 2008. She is currently Associate Professor of Neurology at Oregon Health & Science University and Adjunct Research Associate Professor of Neurology at University of Michigan.  Before joining the OADC, she was a faculty member jointly with the Department of Epidemiology and the Department of Biostatistics at University of Pittsburgh. She is a member of the Executive Council of OADC, and a Data Core Steering Committee member (Chair 2011-2012) for the National Alzheimer's Coordinating Center, established by the National Institute on Aging in 1999 to facilitate collaborative research among the 29 NIA-funded Alzheimer's Disease Centers nationwide.

Dr. Dodge’s research has been focused on three areas. One is to distinguish normal cognitive aging from pathological cognitive decline. She is refining statistical methods which allow us to capture the decline leading to dementia at the earliest stage of the disease. Another is to examine lifestyle and environmental factors leading to healthy cognitive aging. She has been conducting a cohort study in Okinawa, Japan, collaborating with researchers of the Okinawa Centenarian Study. Finally, she is interested in behavioral prevention trials against cognitive decline. She is currently conducting an NIH-funded prevention study to examine whether stimulations through social interaction could improve cognitive function.  She holds Fellow status at the Gerontological Society of America and serves as a statistical editor for several dementia related journals.
