Hi, I'm Nathan Fulton!

Professional Bio

I am a Manager at the MIT-IBM AI Lab in Cambridge, MA. Right now I'm spending a lot of my time Mellea, a library for writing generative programs.

I earned a Ph.D. from Carnegie Mellon University's Computer Science Department, where I was a member of André Platzer's Logical Systems Lab and a core developer of the KeYmaera X theorem prover for hybrid systems. KeYmaera X demonstrates how formal methods techniques can improve the safety and trustworthiness of autonomous planes, magnetic control systems, and embedded devices.

During my first stint at IBM Research, I continued work in this direction -- using hybrid systems verification tooling to build verifiable safety guarantees for reinforcement learning algorithms.

I was then a Senior Applied Scientist at Amazon Web Services for a couple of years, where I worked on CodeWhisperer, an ML-powered coding companion.

I'm now back at IBM Research working on generative computing.
