Research Statement
<p>I am trained in the design and analysis of clinical trials and observational studies. </p>
<p>My students and I develop methods that increase a study’s efficiency and effectiveness. Our current emphasis is in developing covariate-adjusted randomization and sample-size adaptive monitoring methods. </p>
<p>These methods reduce on average the noise in estimating an effect, improve the ability to study key subgroups, and allow for following studies until drawing clinically meaningful conclusions regarding the strength of the true effect.</p>
