Aaron Brown primarily works in smooth hyperbolic dynamics, nonuniform hyperbolicity, and smooth ergodic theory. His recent work focuses on smooth group actions. He often applies tools from smooth dynamics and smooth ergodic theory to study rigidity phenomena for actions of large groups. In particular, he is interested in measuring rigidity questions and problems related to the rigidity of lattice actions and the Zimmer Program, which, in its broadest form, seeks an understanding of actions of large groups on compact manifolds.
Brown’s research has appeared in the Journal of the American Mathematical Society and will soon be published in the Annals of Mathematics.
He received his PhD in mathematics from Tufts University. He also earned a bachelor of arts degree from Oberlin College. He held a National Science Foundation Postdoctoral Research Fellowship at Pennsylvania State University. Most recently, he was an L. E. Dickson Instructor in the Department of Mathematics at the University of Chicago.
