He is a fellow of the American Mathematical Society since 2012.

He is the author of the 1992 book Subgroups of Teichmüller Modular Groups.

Among his contributions to mathematics are his classification of subgroups of surface mapping class groups, and the establishment that surface mapping class groups satisfy the Tits alternative.
