I work at Anthropic, an AI safety and research company in San Francisco, building reliable, interpretable, and steerable AI systems.
At the Autonomy, Agency, and Assurance Institute, I helped to reimagine cybernetics for the 21st century. How can we take cyber-physical systems safely to scale when they embed sensing, learning, and communications in everything from cars to hospitals to elections to intimate relationships?
I also volunteer for community organisations. I'm on the board of the ACT Conflict Resolution Service and the executive of Effective Altruism ANU; less formally I co-organise the Canberra Python meetup and mentored sprints at many conferences.
I regularly contribute to open source software, which empowers users and invites them to become creators, and have been recognised as a PSF Fellow. Lately I've focussed on making software testing easier and much more effective. I'm a core developer of Hypothesis (and some extensions) and a Pytest maintainer. I started hypofuzz.com to support open source development and sell next-generation testing and verification tools.
I often speak at conferences, and most of my public presentations are listed here. Highlights include introducing property-based testing at PyCon US, an expert deep-dive at PyCon Australia (transcript), and winning an AMOS presentation prize for my Honours research characterising Indigenous seasons (poster, thesis).
