Jean-Luc Rabideau, a first-year Ph.D. student who was awarded this week with a Graduate Research Fellowship from the NSF.

The title of his NSF proposal is “Representation stability of congruence subgroups of braid groups.” This project aims to study geometric objects called braids using tools from group theory and representation theory. The goal is to understand patterns that persist as we add more and more strands to the braids. This semester, Jean-Luc has been working with Denis Osin to prove a different result in geometric group theory, namely that a very broad class of symmetry groups (called non-Archimedean Polish groups) can all be realized as outer automorphism groups.

Congratulations, Jean-Luc!
