Bjorn Mikhail Poonen is a mathematician, four-time Putnam Competition winner and currently the Claude Shannon Professor of Mathematics at MIT.[1] His research is primarily in number theory and algebraic geometry, but he has occasionally published in other subjects such as probability[2] and computer science.[3] He has edited two books,[4][5] and his research articles have been cited by approximately 500 distinct authors.[6] He is the founding managing editor of the journal Algebra & Number Theory,[7] and serves also on the editorial boards of Involve[8] and the A K Peters Research Notes in Mathematics book series[citation needed].
Education
In 1989, Poonen graduated from Harvard with an A.B. in Mathematics and Physics, summa cum laude.[citation needed] He then studied under Kenneth Alan Ribet at the University of California, Berkeley, completing a Ph.D. there in 1994.[9]
Academic positions
Poonen held postdoctoral positions at MSRI and Princeton University and served on the faculty of the University of California, Berkeley from 1997 to 2008, before moving to MIT.[citation needed] He has also held visiting positions at the Isaac Newton Institute (1998 and 2005), the Université Paris-Sud (2001), Harvard University (2007), and MIT (2007).[citation needed]
