- Aging & geriatrics: biostatistics; dementia; Alzheimer's disease
- Mental health: biostatistics
A 2007 graduate of the University of Washington's biostatistics program, Rod Walker is quickly developing a unique niche at Group Health Research Institute (GHRI). With interests ranging from breast cancer to dementia to pharmaco-epidemiology, Mr. Walker is poised to strengthen his expertise through a diverse research portfolio.
Mr. Walker is especially interested in working with data from the Adult Changes in Thought (ACT) study to bolster knowledge of risk factors related to dementia and Alzheimer's disease. He is contributing to medication use analyses within this cohort and exploring ways to augment dementia data with neuropathology data. Mr. Walker also works with the Statistical Coordinating Center for the National Cancer Institute's Breast Cancer Surveillance Consortium to organize the collection, management, and analysis of data from seven mammography registries. He recently embarked on new investigations of potential associations between the use of different medication classes and the risk for community-acquired pneumonia in the elderly with GHRI investigator and epidemiologist, Sascha Dublin, MD, PhD.
Mr. Walker is fortunate to have GHRI investigator Sebastien Haneuse, PhD, as a mentor in a wide range of statistical areas, including the design and implementation of two-phase studies, as well as methods for adjusting for selection bias. He looks forward to learning new statistical methods through additional coursework and seminars and is also excited to expand on his graduate thesis work, applying self-modeling regression to pulsewave data in cardiovascular studies. Mr. Walker is a member of the American Statistical Association.
