I am a researcher at the UC Berkeley Center for Long-Term Cybersecurity, where I direct the Daylight Lab ( I received my Ph.D. from the UC Berkeley School of Information. My adviser was John Chuang.

I study cybersecurity. My perspective is heavily informed by science and technology studies (STS), and my methods combine design research and data science.

Some of my recent work:

MLFailures - Helping students identify (and ameliorate) bias in machine learning models.

Measuring Internet Fragmentation - Finding correlates of state power through Internet measurement.

Adversary Personas - Helping people (with or without security expertise) identify the security threats that matter to them.
