Joel Hass is an American mathematician and a professor of mathematics and at the University of California, Davis. [1] His work focuses on geometric and topological problems in dimension 3.
Hass received his Ph.D. from the University of California, Berkeley in 1981 under the supervision of Robion Kirby. [2] He joined the Davis faculty in 1988. [1]
In 2012 he became a fellow of the American Mathematical Society. [3] From 2010 to 2014 he served as the chair of the UC Davis mathematics department. [4]
Hass is known for proving the equal-volume special case of the double bubble conjecture, [5] for proving that the unknotting problem is in NP, [6] and for giving an exponential bound on the number of Reidemeister moves needed to reduce the unknot to a circle. [7]
