## Some of our current PGR students

#### Graham Campbell

Graham’s primary areas of interest are algebra and theoretical computer science, especially (graph) rewriting systems, (geometric) group theory, semigroup theory, automata and formal languages, and decision problems.

#### Sam Mutter

Sam is currently researching the connections between higher-rank graphs, Bruhat-Tits buildings, and geometric group theory, with a particular emphasis on cube complexes.

#### Amos Ajibo

Amos's research interests include Mathematical analysis, in particular, interpolation problems, complex analysis, analytic functions theory and wavelet theory. Their PhD research project is investigating Interpolation problems and quasi-Cartan domains

#### Jack Aiston

Jack’s research interest is in Homomorphic encryption in algebraic structures.

#### Joseph Dessi

Joseph's primary areas of interest are in C*-algebra and operator theory, as well as the theory of Hilbert C*-modules. His PhD research project focuses on investigating the structure of C*-algebras of product systems.
