Dennis Arnold Hejhal (born December 10, 1948, in Chicago) is an American mathematician. In his mathematical research he frequently uses extensive computer calculation.

In 1967, as a college freshman, Hejhal scored among the top 5 in the U.S. in the William Lowell Putnam Mathematical Competition.[1] Hejhal graduated from the

Harvard in 1972, then in 1974 an associate professor at Columbia University and starting in 1978 a professor at the University of Minnesota. Additionally, he was a professor at the Uppsala University from 1994 to 2012 (where he has since been a professor emeritus) and a fellow of the Minnesota Supercomputing Institute since 1986. He was a guest professor at Princeton University in 1993 and at the Institute for Advanced Study
on several occasions since 1983.

Hejhal works on

automorphic forms, the Selberg trace formula and quantum chaos
. From 1972 to 1974 he was a Sloan Fellow. In 1986 he was an
Swedish Academy of Sciences and in 2005 the Eva and Lars Gårding Prize. He is a member of the Swedish Royal Society of Sciences. In 2012 he became a fellow of the American Mathematical Society.[2]

Among his successful former doctoral students is Persi Diaconis. He also supervised the undergraduate honors thesis research of James Z. Wang.
