I'm a Graduate Research Assistant in Computer Science at UT Austin,
working in Security, Software Engineering and Program Analysis.
I'm very passionate about programming, finding ways to break programs, and
building tools for automatically detecting bugs and vulnerabilities.
My research consists in developing program analysis tools for detecting:
Denial-of-Service vulnerabilities in PHP applications (published in CCS '15).
Privacy leaks in PHP applications.
Functional and Performance bugs in Java applications (published in PLDI '15).
I'm always learning new technologies and developing prototypes that I intend to grow into mature research projects.
The following are some of my recent side projects:
BluPhish: A Bluetooth security diagnostic tool.
Microsoft Inc. (Redmond, WA.) Software Development Engineer Intern, June 2015-August 2015. Implemented a diagnostics tool for addressing customer account access incidents in Visual Studio Online, using HTML/JS/CSS and C#.
Bell Labs (Murray Hill, NJ.) Enabling Computing Technology Research Intern, June 2013-August 2013. Generated correctness proofs for standard compiler optimizations in LLVM. PI: Kedar Namjoshi.
Open-source project contributions:
Apache Collections: Proposed a collection algorithm that requires linear-time instead of quadratic-time, resulting in speed-ups larger than 200x. Reported performance bugs and proposed patches. Report IDs: COLLECTIONS-549, COLLECTIONS-534, COLLECTIONS-544, COLLECTIONS-545.
Apache Ant: Reported performance bugs and proposed patches. Report IDs: 57588.
Google Core Libraries: Reported performance bugs and proposed patches. Report IDs: 1868.
jEdit: Reported performance bugs and proposed patches for the IDE. Report IDs: 3904,3908.
