Michael Howard Harris (born 1954) is an American mathematician known for his work in number theory. He is a professor of mathematics at Columbia University and professor emeritus of mathematics at Université Paris Cité. In 2025, he was elected to the American Philosophical Society.[1]

Early life and education

[edit]

Harris was born in Kingsessing, Philadelphia, Pennsylvania[2] and is of Jewish descent.[3] He received his B.A. in mathematics from Princeton University in 1973.[4] He received his M.A. and Ph.D. in mathematics from Harvard University under the supervision of Barry Mazur in 1976 and 1977 respectively.[4][5]

Career

[edit]

Harris was a faculty member at Brandeis University from 1977 to 1994.[4] In 1994, he became a professor of mathematics at Paris Diderot University and the Institut de mathématiques de Jussieu – Paris Rive Gauche, where he has been emeritus since 2021.[4][6] He became a professor of mathematics at Columbia University in 2013.[4]

He was a member of the Institute for Advanced Study from 1983 to 1984 and in the fall of 2011.[7] He has held visiting positions at various institutions, including Bethlehem University, the Steklov Institute of Mathematics, the Institut des Hautes Études Scientifiques, Oxford University, and the Mathematical Sciences Research Institute.[4]

His former doctoral students include Laurent Fargues and Gaëtan Chenevier.[5]

He has organized or co-organized more than 20 conferences, workshops, and special programs in his field of number theory.[8]

Work

[edit]

Research

[edit]

Harris's research focuses on arithmetic geometry, automorphic forms, L-functions, and motives.[9] He has developed the theory of coherent cohomology of Shimura varieties and applied it to number theoretic problems on special values of L-functions, Galois representations, and the theta correspondence.[2] His later work focuses on geometric aspects of the Langlands program.[2]

In 2001, Harris and Richard Taylor proved the local Langlands conjecture for GL(n) over a p-adic local field [10] The Sato–Tate conjecture and its generalization to all totally real fields was proved by Laurent Clozel, Harris, Nicholas Shepherd-Barron, and Richard Taylor under mild assumptions in 2008,[11][12][13] and completed by Thomas Barnet-Lamb, David Geraghty, Harris, and Taylor in 2011.[14]

Mathematics without Apologies

[edit]

Harris wrote the book Mathematics without Apologies: Portrait of a Problematic Vocation, published in 2015.[15][16][17][18]

Silicon Reckoner

[edit]

Since 2021, Harris has written the newsletter Silicon Reckoner exploring questions and issues related to the mechanization of mathematics and artificial intelligence.[19]

Recognition

[edit]

Harris received the Sophie Germain Prize (2006),[4] the Clay Research Award (joint with Richard Taylor, 2007),[2][20] the Grand Prix Scientifique de la Fondation Simone et Cino del Duca (2009),[4] He is a two-time invited speaker at the International Congress of Mathematicians (2002, 2014).[4]

Harris was a Sloan Research Fellow (1983–1985) and a member of the Institut Universitaire de France (2001–2011)[4][2] He has been elected a Member of the Academia Europaea (2016),[4] Fellow of the American Mathematical Society (2019),[4][9] Member of the American Academy of Arts and Sciences (2019),[4] and Member of the National Academy of Sciences (2022).[2][4]
