## Martha Precup

I am an Assistant Professor in the department of mathematics and statistics at Washington University in St. Louis. My primary research interests are in algebraic geometry, combinatorics, and representation theory. Much of my work involves using Lie theory to strengthen and develop connections between combinatorics and geometry. I received my PhD from Notre Dame in 2013 under the direction of Sam Evens. Feel free to contact me with any questions or check out my CV.
