Carl M. Bender (born 1943) is Wilfred R. and Ann Lee Konneker Distinguished Professor of Physics at Washington University in St. Louis.
Bender received his B.A. in 1964 from Cornell University, where he graduated summa cum laude and with Distinction in All Subjects and was elected to residence in the Telluride House. He earned his M.A. and Ph.D in physics from Harvard University in 1965 and 1969, respectively. He was a visiting scholar at the Institute for Advanced Study in 1969-70.
Bender's research has focused on quantum mechanics and quantum field theory. Since 1998, his work has examined in depth a new field of physics known as PT Symmetric Quantum Mechanics (PTQM). Bender has often given public talks on a number of areas including: quantum mechanics, quantum field theory, black holes, global warming and theoretical physics. He is an expert on lower-dimensional quantum field theories, which he refers to as "country-style quantum physics".
He won a Guggenheim Fellowship in 2003 for his work in lower-dimensional quantum field theory. In 1978 he was elected as a Fellow of the American Physical Society. In 2007 Professor Bender held the Ulam Fellowship at the Center for Nonliner Studies at Los Alamos National Laboratory. He received the Fulbright Fellowship and Lady Davis Fellowship (visiting professor) in 1995. In 2017, Professor Bender won the Dannie Heineman Prize for Mathematical Physics, a prize jointly awarded by the American Physical Society and the American Institute of Physics.
