I co-founded Adept. We built the first computer use agents and the Fuyu family of multimodal models. We exited to Amazon, where I am now a scientist.

I am the lead inventor of the Scratchpad technique (see tweet) for enabling transformers to perform multi-step reasoning. This technique, now commonly known as chain of thought, is the foundation of all modern AI reasoning systems. I jointly hold the patent for chain of thought.

During my PhD, I spent time at Google Brain, working with my Adept co-founder Augustus Odena. In addition to Scratchpad, we also did some of the early work using large language models to automatically write programs.

I received my PhD from MIT. I was advised by Josh Tenenbaum and Armando Solar-Lezama. I also worked with Brenden Lake (NYU/Facebook AI) and Jacob Andreas. My research focus at MIT was program synthesis: using deep learning as well as symbolic techniques to automatically write programs.

I’ve also spent time as an intern at Facebook AI Research.

Before MIT, I studied physics at Harvard.
