Thomas W TuckerThomas W. Tucker is the Charles Hetherington Professor of Mathematics at Colgate University, where he has been since 1973, after a PhD in 3-manifolds from Dartmouth in 1971 and a postdoc at Princeton (where his father A. W. Tucker was chairman and Jon Nash's thesis advisor). He is co-author (with Jonathan Gross) of Topological Graph Theory. His early publications were on non-compact 3-manifolds, then topological graph theory, but his recent work is mostly algebraic, especially distinguishability and the group-theoretic structure of symmetric maps.
