About me

I am a sixth year computer science Ph.D student at Duke University, advised by Dr. Landon Cox. My research interests are broadly in systems and I have worked on a wide variety of projects. My most recent project is SandTrap, a Dynamic Information Flow Tracking system for native code on Android.

That said, I am very much interested in the total sum of knowledge, whether economics, philosophy, history, or theatre. Why stay constrained to Computer Science? The universe is certainly a lot larger. I am always on the lookout for inter-disciplinary projects to work on and if you have any great ideas, please contact me. I would love to hear from you!

Other events and things

I recently attended Microsoft Research's Student Summit on Mobility, Systems, and Networking. I presented a short talk on HotMobile `16 work (the precursor to SandTrap).
