Zac is the lead maintainer of the Hypothesis project, a PSF Fellow, and generally enjoys contributing to open-source communities. Earlier this year he moved from Australia to SF, where he works as a research engineer at https://anthropic.com, helping to build reliable, interpretable, and steerable AI systems.

When away from a computer - it happens! - Zac can often be found in the great outdoors, or relaxing with a good book and a block of dark chocolate.
