My projects focus on e-crime (fraud, abuse) and user-centric web/network security/privacy measurement. My interests are widespread across security, privacy, and distributed systems, but I'm particularly interested in improving the WebPKI and making security user-friendly and accessible.
I have a number of fun ongoing projects, some in collaboration with Microsoft, Google and others. I'd love to talk more about my work, yours, or how the two overlap-- just contact me!
I am a PhD candidate with the Center for Evidence-based Security Research (CESR), and part of the Systems and Networking and Cryptography and Security groups at UC San Diego.
I received my MS in CS from UCSD in July of 2013. I also hold a BS with honors in CS from the wonderful Harvey Mudd College.
Tripwire is a method for detecting website compromises as an unprivileged third-party using externally-visible side effects. Our proof-of-concept implementation exposed previously-unknown compromises impacting more than 100 million users.
This work explored search advertiser fraud on Microsoft's Bing search engine, characterizing the scale of fraud, the targeting and bidding behavior of fraudsters, and how those fraudsters impact legitimate advertisers in the ecosystem.
In summer 2017, I co-designed and taught CSE 80, covering essential Linux/UNIX command line skills for all computer scientists and software engineers. The course is highly interactive, taking place entirely at a traditional Bash command prompt.
I have also previously TA'd CSE 223B (Graduate Distributed Computing & Systems) and CSE 30 (Computer Organization & Systems Programming).
I have a number of side projects working on making the internet safer and more private. Until April 2018, I was also the primary maintainer of Chez Bob.
When not on a computer, I try to spend as much time outside as possible.
