## Early life and education

Pixton was born in Binghamton, New York; his father, Dennis Pixton, is a retired professor of mathematics at Binghamton University. He grew up in Vestal, New York. While a student at Vestal Senior High School, he scored a perfect score on the American Mathematics Competition three times from 2002–2004.[1] He went on to the International Mathematical Olympiad in 2003 and 2004 to win consecutive gold medals.[2]

While an undergraduate at Princeton University, Pixton was a three-time Putnam Fellow. For his research conducted as an undergraduate, he was awarded the 2009 Morgan Prize.[3] In 2008, he received a Churchill Scholarship to the University of Cambridge.[4] Pixton received his Ph.D. in 2013 from Princeton under the supervision of Rahul Pandharipande; his dissertation was *The tautological ring of the moduli space of curves*.[5]

## Career

Pixton was appointed as a Clay Research Fellow for a term of five years beginning in 2013.[6] After two years as a postdoctoral researcher at Harvard University, he became an assistant professor of mathematics at the Massachusetts Institute of Technology in 2015.[7] In 2017 he won a Sloan Research Fellowship.[8]

## Chess

Pixton is also a former child prodigy in chess. He was the 2001 U.S. Cadet Champion,[9] the 2002 US Junior Chess Champion,[10][11] and had a win against the former US Champion Joel Benjamin in 2003.[12]
