## Personal profile

### Personal Statement

I am a Reader in Combinatorics and the Director of Internationalisation in the Department of Computer and Information Sciences.

My research interests are in Combinatorics, Graph Theory, Discrete Analysis and Formal Languages.

Recent research has included studies in the theory of patterns in combinatorial structures and the theory of word-representable graphs. In paritcular, my book *Patterns in Permutations and Words*, published by Springer (EATCS monographs in Theoretical Computer Science book series) in 2011, is the first comprehensive source over results and trends in the fast-growing field of patterns in permutations and words. My other book *Words and Graphs,* published by Springer (EATCS monographs in Theoretical Computer Science book series) in 2015, is a comprehansive introduction to the theory of word-representable graphs.
