I recently graduated with my Ph.D. in Computer Science at UC Berkeley. I was advised by David Wagner and have been supported by the NSF Graduate Research Fellowship and the Intel Science and Technology Center for Secure Computing (ISTC). I received my MS in Computer Science from UC Berkeley and my BS in Computer Science with a minor in Engineering Business from the University of Virginia.

My research is in computer security and primarily focused on mobile phone security and static analysis.

I am excited to announce that I will be joining Twitter in the fall.

At UC Berkeley, I have been a Graduate Student Instructor for CS 161 Computer Security (Spring 2010) for David Wagner and Vern Paxson and a tutor at the Self-Paced Center (Spring 2012).

At the University of Virginia, I was a TA for CS 216 Program and Data Representations for five semesters. I have worked with Ruth Anderson, Tom Horton, Dave Evans, and Michele Co. For this work, I received UVA's Undergraduate Education Award.

Life Outside of Soda Hall

As much as I love research, it's always good to take a break. In my spare time, I enjoy ballroom dancing, zumba, yoga, ballet, cooking, and traveling.
