I’m a PhD student in computer science at the University of Maryland, College Park. My research focuses on security for mobile devices using a combination of systems and language based techniques. I’m a member of the PLUM group, advised by Jeff Foster. I also routinely collaborate with the rest of the members of the PLUM lab and Michael Clarkson.
You can find a list of my publications on my Google Scholar profile. You may also be interested in the lab’s Github page.
Major projects I’ve worked on include:
The Redexer binary rewriter, with Jinseong Jeon and our collaborators. Redexer instruments Dalvik binaries (the executable format for Android apps), which we used for finer grained permissions and measuring utility of apps with fuzzed inputs.
Temporal Logics for Hyperproperties which seeks to develop logical foundations for security statements that quantify over multiple executions of a program and relate those executions using predicates. This work allows stating a wide variety of statements about program security, such as noninterference and observational determinism.
GUI based declassification for Android. My current work applies static analysis to Android programs, using declassification policies based on user inputs.
