Nathan Dunfield is an American mathematician specializing in low-dimensional topology and geometric group theory. He is a professor in the Department of Mathematics at the University of Illinois Urbana-Champaign. His research focuses on the geometry and topology of 3-manifolds, hyperbolic geometry, and computational aspects of geometric topology. Dunfield has contributed to the development and application of computational tools in topology, including work with the software SnapPy for studying hyperbolic 3-manifolds.
He received his Ph.D. from the University of Chicago in 1999 under the supervision of William P. Thurston. Dunfield has authored numerous research papers, many in collaboration with other prominent mathematicians such as William Thurston, Dylan Thurston, and Marc Culler. He has also supervised graduate students and contributed to educational initiatives in mathematics.
Dunfield has held academic positions at several institutions, including Harvard University and the California Institute of Technology, prior to joining the University of Illinois. He has been supported by grants from the National Science Foundation and has served on editorial boards for mathematical journals.
