Research Statement

I am trained in the design and analysis of clinical trials and observational studies. We develop study design methods which increase a study’s efficiency and effectiveness.

Primary methods include covariate-adjusted randomization and sample-size adaptive monitoring. These methods help reduce signal noise, improve the ability to study key subgroups, and follow studies until drawing clinically meaningful conclusions regarding the strength of the true effect.
