Key Responsibilities
 Director of Admissions for the School of Mathematics, University of East Anglia (20172021)
Teaching Interests
I have taught a range of mathematics courses at UEA including: firstyear Linear Algebra, Algeba I: Group Theory, Mathematical Skills, and the module Sets, Numbers and Proof; secondyear Ring Theory, and Further Linear Algebra, and the thirdfourthyear modules Semigroup Theory, and Galois Theory.
Key Research Interests
I am an algebraist with interests in a wide range of topics including: combinatorial and geometric group and semigroup theory, algorithmic problems for groups and monoids, homological finiteness properties, algebraic combinatorics, groups acting on graphs and other relational structures, and homogeneous structures in the modeltheoretic sense.
