The GATAS Lab The GATAS Lab

The lab is a mix of backgrounds – dynamics and control, high-performance computing, category theory, programming languages – and we are always looking for students and researchers who want to make scientific models composable enough to build out of parts.

We are hiring

The lab is accepting PhD students, postdocs, research scientists, and undergraduate researchers.
