Presidential Teaching Professor
Ph.D., University of Warwick — Geometric Function Theory and Dynamics
Fletcher’s research weaves together complex analysis, geometry, topology and dynamics in the study of quasiconformal and quasiregular mappings. A central focus is quasiregular dynamics — a rich generalization of complex dynamics to higher dimensions — where he investigates Julia sets, Cantor sets, escaping sets and linearization problems. He also works in Teichmüller theory, including infinite-dimensional Teichmüller spaces. Fletcher is co-author of the Oxford University Press graduate textbook Quasiconformal Maps and Teichmüller Theory, has published in the Transactions of the American Mathematical Society, Geometric and Functional Analysis, Ergodic Theory and Dynamical Systems and the Bulletin of the London Mathematical Society and has been supported by the Simons Foundation and an EPSRC Postdoctoral Research Fellowship.
