Research Overview

My research interests include a commitment to the assessment of outcomes in our pediatric and adult congenital cardiac patients. This encompasses ways to improve care for patients undergoing cardiac and non-cardiac surgery. In addition, I maintain an interest in large data, and the methodology to improve data quality in large data sets.
