I direct the Daylight Lab at the UC Berkeley Center for Long-Term Cybersecurity. I am also a worker-owner of DAO DAO, a co-op that builds co-ops.

I perform strategic foresight on the future of information technology. My work has shaped practice at a variety of institutions, including CISA, Meta, and the Internet Society. If you’re interested in working with me, please email me at:

Public projects

In reverse-chronological order of when I began work on each):

  • Internet Atlas - Real-time data and analysis about who controls the global internet. This work has been integrated into Internet Society's Pulse dashboard, covered by CNN, and used by the intelligence community.

  • MLFailures - Open-access materials to teach students, policymakers how to identify and ameliorate bias in machine learning models. I have taught versions of these materials are used to graduate students, business leaders, and government officials.

  • Adversary Personas - A game to help non-experts identify security threats. This practice has been integrated into Meta’s threat ideation process, and into the U.S. Cybersecurity and Infrastructure Security Agency (CISA)'s participatory threat modelling process.

  • Passthoughts - Using brain-machine interface to “think your password.” Passthoughts was the world's first one-step, three-step authentication mechanism, and has been widely-covered in the media (see a partial list here).

Big ideas

I have developed a couple of “Big Ideas” over the years.

About me

I received my Ph.D. from the UC Berkeley School of Information. My adviser was John Chuang.

All of my papers should be available on Google Scholar without a paywall. If you find a paper you can’t access, please let me know.

I live in xučyun, Ohlone territory. If you do too, check out cafe mak-’amham and consider giving Shuumi.
