Research

Overview

I'm working as a software engineer at AWS.

I completed my Ph.D. at UMD working with professors Michael Hicks and Jeffrey Foster. As a graduate student, my research focused on tools and techniques to help developers safely apply dynamic software updating. In particular, my research aims to provide an improved understanding of the challenges posed by run-time updates, such as ensuring update correctness, and to reduce the developer effort required to address those challenges.
