Bjorn Poonen
From Wikipedia, the free encyclopedia
Bjorn Poonen is a mathematician, currently in the mathematics department of the University of California, Berkeley, where he is Professor and a Vice Chair for Undergraduate Affairs.[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 300 distinct authors.[6] He is the founding managing editor of the journal Algebra & Number Theory[7], and serves also on the editorial boards of International Mathematics Research Notices[8], Involve[9], the Journal of the American Mathematical Society[10], the London Mathematical Society Journal of Computation and Mathematics[11], and the A K Peters Research Notes in Mathematics book series[citation needed].

[edit] 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.[12]
[edit] Academic positions
Poonen held postdoctoral positions at MSRI and Princeton University before moving to the University of California, Berkeley in 1997.[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]
[edit] Major honors and awards
- David and Lucile Packard Fellowship[13]
- Sloan Research Fellowship[14]
- William Lowell Putnam Mathematical Competition: winner in 1985, 1986, 1987, and 1988 (the only other four-time winners since 1938 are Don Coppersmith, Arthur Rubin, Ravi D. Vakil, Gabriel Carroll, Reid W. Barton, and Daniel Kane).[15]
- International Mathematical Olympiad: silver medalist in 1985.[16]
- American High School Mathematics Examination: only participant (out of 380,000) to receive a perfect score in 1985.[17]
[edit] Trivia
- Poonen is cited in the Wikipedia page on the number 12.
- He co-authored a paper entitled "How to spread rumors fast".[18]
- His Erdős-Bacon number is 5: he co-authored scholarly articles with Andrew Granville[19], Wen-Ch'ing Winnie Li[20], Andrew Odlyzko[21], and Peter Winkler[22], all of whom have Erdős number 1[23]; and he appeared in the documentary Julia Robinson and Hilbert's Tenth Problem[24] narrated by Danica McKellar, who has Bacon number 2.[25]
