Gabriel Carroll
Gabriel Drew Carroll (born December 24, 1982)[2] is a Professor of Economics at the University of Toronto.Carroll won two gold medals (1998, 2001) and a silver medal (1999) at the International Mathematical Olympiad (IMO), earning a perfect score at the 2001 International Mathematical Olympiad held in Washington, D.C., shared only with American teammate Reid W. Barton and Chinese teammates Liang Xiao and Zhiqiang Zhang.[5][6][7] Gabriel earned a place among the top five ranked competitors (who are themselves not ranked against each other) in the William Lowell Putnam Competition all four years that he was eligible (2000–2003),[8] a feat matched by only seven others (Don Coppersmith (1968–1971), Arthur Rubin (1970–1973), Bjorn Poonen (1985–1988), Ravi Vakil (1988–1991), Reid W. Barton (2001–2004), Daniel Kane (2003–2006), and Brian R. Lawrence (2007–08, 2010–11).His top-5 performance in 2000 was particularly notable, as he was officially taking the exam in spite of only being a high school senior, thus forfeiting one of his years of eligibility in college.[2] Gabriel Carroll is an alumnus of Oakland Technical High School and graduated from Harvard University in 2005 with degrees in Mathematics and Linguistics.
