I am a CSE Postdoctoral Fellow at UC San Diego, where I work with Geoff Voelker and Stefan Savage.
My research studies computer security, with a particular interest in problems at the intersection of data and security. Currently, my work focuses on establishing a data-driven foundation for "threat-hunting": I develop new algorithms, systems, and empirical insights that enable organizations to uncover and thwart sophisticated attacks.

Previously, I graduated with my Ph.D. from UC Berkeley, where I was advised by Vern Paxson and David Wagner. My research was supported in part by a Facebook Ph.D. Fellowship and an NSF Graduate Research Fellowship. Before graduate school, I received my Bachelors in computer science from Stanford University.

Teaching Experience

Work Experience

In the past I've interned on Google's Safe Browsing Team, where I worked on web malware detection (2013), binary analysis (2014), and applying ML to detect social engineering attacks (2017); my mentors were Brad Miller, Moheeb Rajab, Lucas Ballard, and Niels Provos. More recently in 2018, I worked as a research intern at Barracuda Networks with Asaf Cidon and Lior Gavish to study and develop defenses against lateral phishing attacks. During my undergraduate years, I also studied web and mobile security topics with Dan Boneh, and spent a summer developing software for Android devices in Ron Fedkiw's graphics lab and at Amazon's Lab 126.


At Berkeley, I started an external security speaker series, the Berkeley Security Seminar, and organized it from Spring 2015 - Fall 2018. If you're interested in giving a technical or policy talk on interesting security and privacy problems, please visit the seminar website to contact the current organizers. I served as an external reviewer for Usenix Security 2020, CCS 2019, Usenix Security 2019, NDSS 2016, and ACM TWEB 2016.


Several years ago, I used to be an active chess player. My USCF rating is 2111 and I am a two-time US National co-champion (tied for first) in the 8th grade and 9th grade divisions. I've also won first place at the Florida State Chess Championship a few times; the high school division in 2008 (as a 10th grader) and the middle school division in 2005. Currently, I spend a lot of my time as a researcher and student, but I enjoy occasionally playing blitz and watching the games of some of my favorite players (Carlsen and Topalov) at the latest tournaments. My favorite book is "Play like a Grandmaster" by Kotov and one of my favorite games is Kramnik vs. Topalov at Corus 2005.
