I am a fifth-year computer science graduate student at UC Berkeley advised by Raluca Ada Popa. I was a research intern at Signal Messenger last summer. My interests are broadly in security and systems. I am grateful to be supported by an NSF-GRFP fellowship.

I completed my B.S. in Electrical Engineering & Computer Science at UC Berkeley, where I worked with Scott Shenker, Aurojit Panda, and Justine Sherry in NetSys.
