I’m currently the course instructor of 595G, Seminar in Computer Security at the University of California, Santa Barbara. Previously, I was a founding member and blockchain security auditor at OtterSec and a quantitative researcher at Zellic.

I’d like to explore as much computer science and pure mathematics as I can. I enjoy making embedded systems, where programmers have creative freedom over hardware, software, and the bridge between the two.

I play Capture-the-Flag competitions with the United States’ #1 competitive cybersecurity team, DiceGang, and practice for the International Cybersecurity Competition with the U.S. Cybersecurity Team. Sometimes, I work with government organizations like the United States AFA, Aéroports de Paris, Saudi FCSP and UAE Cybersecurity Council as well as blockchains like Solana, Sui, and Aptos to make the internet safer.

As a researcher, I’ve done guest lectures on exploitation at the HOPE Conference, Carnegie Mellon University, and EPFL Innovation Park. This summer, I’ll be working with the picoCTF team at Carnegie Mellon University’s REU. One day, I hope to be a professor.

I write about interesting technical problems and ideas on my blog.
