My research interests are eclectic, including: Dynamic Information Flow Tracking,
Reverse Engineering, Network Measurement, and Internet Censorship.
I am currently doing a post-doc at UT Austin working with Dr. Tiwari.
I developed the following tool to aid in
learning the function call structure within a program. I had an OTF
fellowship through the ICFP program for a year, where I reversed
engineered LINE to evaluate its cryptography implementation. The
results of which are to be published in the 2017 FOCI workshop, and
