Dr. Sepanski joined the Baylor faculty in 1997. Prior to coming to Baylor, he had postdocs at Oklahoma State University (1995-1997) and Cornell University (1994-1995) after graduating from MIT in 1994. Though being born in Minnestoa and ending up in Indiana, he mostly grew up in Wisconsin. He has been married to Laura Sepanski since 1990 and has three delightful children: Sarah, Benjamin, and Shannon. Besides mathematics, he enjoys gardening with native Texas plants, playing the guitar, Tae Kwon Do, rock climbing, hiking, camping, biking, running, reading fantasy, spending time with his family, and cooking. Dr. Sepanski's research is in Lie theory and, in particular, in representation theory of real reductive Lie groups. Dr. Sepanski has been the Director of Graduate Studies since 2010 and on the Graduate Committee since 2000.
