I am an assistant professor in the mathematics department at the University of Alabama. Prior to my current position, I was a Simons postdoctoral fellow at MSRI, research associate and lecturer at the University of Virginia, NSF postdoctoral fellow at the University of Utah, and a graduate student at the University of Missouri.
