I am a mathematics researcher and educator whose interests include Algebra, Geometric Group Theory, Representation Theory, and Mathematical Physics. My current work is in infinite-dimensional Kac-Moody Lie algebras and their representations. I am currently an Assistant Professor of Mathematics at the University Delaware, where I am helping to advance the missions of the Mathematical Sciences Learning Laboratory (MSLL).
