He works at [Letta](/knowledge/letta) on infrastructure and developer-facing systems for stateful AI agents. Cameron earned a PhD in finance from the University of Oregon and later worked as a postdoctoral researcher at Stanford Graduate School of Business. His economics research has included Bayesian statistics, industrial organization, asset pricing, and market microstructure. He has contributed to [Turing.jl](https://turinglang.org/), an open-source probabilistic programming system written in Julia. His other public work includes AI agent infrastructure, technical writing, [AT Protocol](/knowledge/atproto) projects, and tools for persistent machine memory. Before his academic and software work, Cameron worked as an alpaca rancher and for Cirque du Soleil.
