Staff Profile

Professor Sarah Rees

Professor of Pure Mathematics


I am a Professor of Pure Mathematics for School of Mathematics, Statistics & Physics at Newcastle University. I work mainly on geometrical, combinatorial and computational aspects of group theory. In particular, I am currently interested in:

  • Decision problems
  • Links between group theory and formal language theory
  • The theory of automatic groups and group combings
  • The language of theoretical complexity of the word problem
  • The theoretical and practical development of algorithms in group theory

Roles and Responsibilities

  •  Member of the EPSRC Peer Review College
