Joseph Lipman

Joseph Lipman (born June 15, 1938) is a Canadian-American mathematician, working in algebraic geometry.

Lipman graduated from the University of Toronto with a bachelor's degree in 1960 and then went to Harvard University, receiving his master's degree in 1961. He then earned a Ph.D. there in 1965 under the supervision of Oscar Zariski. In 1965 he was an assistant professor at Queen's University in Kingston and in 1966 was an assistant professor at the Purdue University, where he became professor in 1971. From 1987 to 1992, there, he was head of the mathematics department. He was a member of the MSRI and visiting scholar at the University of Cambridge and the University of Nice and a visiting professor at the Columbia University and Harvard University.

He specializes in singularity theory in algebraic geometry.

In 1958, while studying at the University of Toronto, he became a Putnam Fellow both in the spring and fall William Lowell Putnam Mathematical Competitions. In 1982 he received the Jeffery–Williams Prize. He is a fellow of the American Mathematical Society.
