Jordan Stuart Ellenberg (born 1971) is an American mathematician who is a professor of mathematics at the University of Wisconsin–Madison.[2] His research involves arithmetic geometry. He received both his A.B. and Ph.D. from Harvard University.

Early life

Ellenberg was born in Potomac, Maryland. He was a child prodigy who taught himself to read at the age of two by watching Sesame Street.[3] His mother discovered his ability one day while she was driving on the Capital Beltway when her toddler informed her: "The sign says `Bethesda is to the right.'" In second grade, he helped his teenage babysitter with her math homework. By fourth grade, he was participating in high school competitions (such as the American Regions Mathematics League) as a member of the Montgomery County math team. And by eighth grade, he had started college-level work.

He was part of the Johns Hopkins University Study of Mathematically Precocious Youth longitudinal cohort. He scored a perfect 800 on the math portion and a 680 on the verbal portion of the SAT-I exam at the age of 12.[4] When he was in eighth grade, he took honors calculus classes at the University of Maryland; when he was a junior at Winston Churchill High School, he earned a perfect score of 1600 on the SAT; and as a high school senior, he placed second in the national Westinghouse Science Talent Search.[5] He participated in the International Mathematical Olympiads three times, winning gold medals in 1987 and 1989 (with perfect scores) and a silver medal in 1988.[6] He was also a two-time Putnam fellow[7] (1990 and 1992) while at Harvard.


In 2004, he began teaching at the University of Wisconsin at Madison and is currently the John D. MacArthur Professor of Mathematics, a position he has held since 2015.[8] In 2012 he became a fellow of the American Mathematical Society and was a plenary speaker at the 2013 Joint Mathematics Meetings where he spoke on the subject of number theory and algebraic topology, the study of abstract high-dimensional shapes and the relations between them.[9][10][11] He was named a Guggenheim Fellow in 2015.[12] His research focuses on "the fields of number theory and algebraic geometry." [13]

In addition to his research articles, he has authored a novel, The Grasshopper King,[14] which was a finalist for the 2004 Young Lions Fiction Award;[15] the "Do the Math" column in Slate;[16] a non-fiction book, How Not to Be Wrong;[17][18][19] and articles on mathematical topics in The New York Times, The Washington Post, The Boston Globe, Wired, Seed, and The Believer.

Personal Life

Ellenberg lives in Madison, Wisconsin, with his wife and children.[13] He maintains a blog called Quomodocumque which means "after whatever fashion" in Latin.[20]
