Bernard Shiffman (born 23 June 1942) is an American mathematician, specializing in complex geometry and analysis of complex manifolds.
Shiffman received in 1964 from Massachusetts Institute of Technology (MIT) a bachelor's degree and in 1968 from the University of California, Berkeley a PhD under Shiing-Shen Chern with thesis On the removal of singularities in several complex variables. Shiffman was at MIT a C.L.E. Moore Instructor from 1968 to 1970 and at Yale University an assistant professor from 1970 to 1973. At Johns Hopkins University he was from 1973 to 1977 an associate professor and is from 1977 a full professor; he was the chair of the department of mathematics from 1990 to 1993 and again from 2012 to 2014. He has held visiting positions in the US, France, Germany, and Sweden.
For the two academic years 1973–1975 Shiffman was a Sloan Research Fellow. From 1993 to 2005 he was editor-in-chief of The American Journal of Mathematics. He was elected a Fellow of the American Mathematical Society in 2012.
His father was the mathematician Max Shiffman.
