I aim to answer pressing clinical questions using research in the comparative pharmacoepidemiology of chronic medications in older adults.

My main therapeutic areas of interest are osteoporosis, diabetes, and hypertension. My methods areas of interest include propensity score methods, causal inference, and self-controlled study designs. I also conduct research on the impacts of drug pricing and policy on medication use, particularly in vulnerable populations.
