Karl Liechty earned his PhD in mathematics in 2010 from Purdue University. After a semester as a postdoctoral scholar at the Mathematical Sciences Research Institute he then spent three years at the University of Michigan, before joining the faculty at DePaul University in 2014.
Liechty's research interests are in random matrix theory and related problems in probability, statistical physics, and integrable systems. In 2015 he was awarded the Gabor Szego prize for outstanding contributions in the area of orthogonal polynomials and special functions by the Society for Industrial and Applied Mathematics (SIAM). In 2015 he was also awarded a Simons Collaboration Grant for Mathematicians from the Simons Foundation.
