Marie-Louise Michelsohn (born October 8, 1941) is a professor of mathematics at State University of New York at Stony Brook.


Michelsohn attended the Bronx High School of Science. She attended the University of Chicago for her undergraduate and graduate studies, including her PhD.

She spent a year as a visiting professor at University of California at San Diego. She spent a year l'Institut des Hautes Études Scientifiques outside of Paris, France. She then joined the faculty of State University of New York at Stony Brook.

Research areas[edit]

Her PhD was in topology. Her research includes complex geometry, including the geometry of spin manifolds and the Dirac operator, and the theory of algebraic cycles. She is credited as the first mathematician to introduce the concept of a balanced hermitian metric into complex geometry.[1][2]

Masters athletics[edit]

Michelsohn is also an accomplished middle and long distance runner. She holds five masters athletics world records including through three age divisions of the 2000 metres steeplechase which she has held since 2002.[3] In addition to the world records, she holds 6 more outdoor American records and 10 indoor American records, running the table of all official indoor distances 800 metres and above in both the W65 and W70 divisions.[4]
