Clinical Research Description
My primary research interest has been in using population-based cohorts and assessing patient-reported outcomes in conditions treated with surgical procedures, specifically prostate cancer. My additional interests include (but are not limited to) cost-effectiveness analyses, exploring disparities in access and quality of care across numerous surgical conditions. I also maintain a focus on improving clinical decision-making.
