Dougherty is a three-time winner of the U.S.A. Mathematical Olympiad (1976, 1977, 1978) and a three-time medalist in the International Mathematical Olympiad.[2] He is also a three-time Putnam Fellow (1978, 1979, 1980).[3] Dougherty earned his Ph.D. in 1985 at University of California, Berkeley under the direction of Jack Silver.[4]

With Matthew Foreman he showed that the Banach-Tarski decomposition is possible with pieces with the Baire property, solving a problem of Marczewski that remained unsolved for more than 60 years.[5] With Chris Freiling and Ken Zeger, he showed that linear codes are insufficient to gain the full advantages of network coding.[6]
