Lucas Mason-Brown
I am an Assistant Professor of Mathematics at UT Austin. Previously, I was a Titchmarsh research fellow in the Mathematical Institute at the University of Oxford and a Nicholas Kurti Junior Research Fellow at Brasenose College. I completed my PhD at MIT in 2020 under the supervision of David Vogan.
I study the connections between representation theory, symplectic geometry, and the Langlands program. I am particularly interested in using geometric tools to study unitary representations of Lie groups.
Here is a talk I delivered at IHES on Arthur’s Conjectures and the Orbit Method.
