Professional Interests

Dr. Wei's area of research expertise is in geriatric pharmacoepidemiology, with specific focus areas on drug safety, drug effectiveness, and quality of medication prescribing in older adults, especially those with pain, neurodegenerative diseases (e.g., Alzheimer’s disease and related dementia [ADRD]), and nursing home stays.  In addition to her research expertise, she will make important contributions to the teaching mission; including graduate student teaching and mentoring, as well as the service mission of the College.
