My research interests lie in semigroup theory, infinite combinatorics, model theory and theoretical computer science. At present, I am studying monoids lying between the automorphism group and endomorphism monoid of first order structures, with a particular emphasis on homomorphism-homogeneity. I plan to investigate more connections between model theory and semigroup theory; in particular, looking at partial map monoids related to first-order structures. In addition, I am looking at classification results for homomorphism-homogeneous structures.
I am an active referee.
