** Research Descriptions **

Dr. Cheng research interests lie in the representation theory of Lie algebras and Lie superalgebras. His studies in the past include the relationship between the representation theory of classical Lie algebras and that of Lie superalgebras of classical types. He is especially interested in understanding the characters of modules over Lie superalgebras in general.
