I am interested in the role of freshwater mussels as ecosystem engineers, in both temperate and tropical freshwater ecosystems, and their interactions with invertebrate communities.  I also study changes to mussel populations as a result of both recent and long-term environmental alteration, and the implications for wider ecosystem functioning.

I am supported by a Whitten Studentship.
