I am a fifth-year Ph.D. student in computer science at UC Berkeley, where I am advised by Vern Paxson and David Wagner. In recent years, I've also worked closely with Stefan Savage and Geoff Voelker. My research studies how we can soundly leverage large-scale data to improve computer security. I develop new data-driven techniques to detect and mitigate attacks, study the applicability and challenges of using machine learning for security purposes, and conduct large-scale empirical analysis to uncover novel insights about the structure of security problems. I am a recipient of a Facebook Ph.D. Fellowship and an NSF Graduate Research Fellowship.

As an undergraduate, I attended Stanford University and graduated with honors in 2014. At Stanford, I researched web and mobile security topics with Dan Boneh. I also served as a teaching assistant for Stanford's computer security course and several other courses in the department.

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 earlier summers, I developed 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 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.
