I am a PhD candidate at the University of California, San Diego in the Department of Computer Science and Engineering. I am advised by KC Claffy and Alex Snoeren. My research interest is in Internet Measurement and Interdomain Routing Security. My current research focuses on routing security and defenses against abuse of the interdomain routing system. I work at the Sysnet and CNS research groups at Computer Science and Engineering, and at CAIDA at the San Diego Supercomputer Center.

Before starting my PhD, I obtained my B.S. in Computer Science here at UC San Diego with a minor in Organic Chemistry (wet labs are fun!).
