Hiroko Dodge has over 20 years of experience working as a biostatistician in the dementia research field. In addition to her statistical expertise, her research interests cover a wide range of areas, including behavioral intervention against cognitive decline, epidemiology of dementia and cross cultural comparisons on healthy aging. Her current NIH funded R01 projects examine whether social interactions through modern communication technologies (e.g., internet and webcams) could improve cognitive functions among socially isolated seniors, recruiting participants from Meals on Wheels programs. She also has been actively conducting research in Japan: she has a research cohort of healthy seniors in Okinawa, Japan, who have been followed since 2007. This cohort has been providing opportunities for researchers to examine factors associated with healthy cognitive aging.
She is the founding chair of a Professional Interest Area (PIA) entitled "Clinical Trials Advancements and Outcomes" in the International Society to Advance Alzheimer's Research (ISTAART, an international AD research organization sponsored by the Alzheimer's Association). This PIA creates an international researchers' forum where innovative clinical trial approaches, developments of outcomes sensitive to trial effects, and unique non-pharmacological trials are being introduced and discussed. She holds Fellow status at the Gerontological Society of America and serves as statistical and senior editors for multiple dementia journals.
