Michael J. Larsen

Michael Jeffrey Larsen is an American mathematician, a distinguished professor of mathematics at Indiana University Bloomington.

Academic biography In high school, Larsen tied with four other competitors for the top score in the 1977 International Mathematical Olympiad in Belgrade, winning a gold medal. As an undergraduate mathematics student at Harvard University, Larsen became a Putnam Fellow in 1981 and 1983. He graduated from Harvard in 1984, and earned his Ph.D. from Princeton University in 1988, under the supervision of Gerd Faltings. After working at the Institute for Advanced Study he joined the faculty of the University of Pennsylvania in 1990, and then moved to the University of Missouri in 1997. Their son Daniel at age 13 became the youngest person to publish a crossword in the New York Times. In 2022, Daniel published a discovery about Carmichael numbers.

Research Larsen is known for his research in arithmetic algebraic geometry, combinatorial group theory, combinatorics, and number theory. and on the representation theory of braid groups.

Awards and honors In 2013 he became a fellow of the American Mathematical Society, for "contributions to group theory, number theory, topology, and algebraic geometry". He received the E. H. Moore Research Article Prize of the AMS in 2013 (jointly with Richard Pink).
