Research Interests

My research interests concern evolution of the Dipnoi (lungfish), in particular, the evolution of sensory functions in this group and closely related organisms. I use microCT scanning techniques to probe the brain cavity and nerve and blood vessel canals in fossilised fish skulls which can then be used to test hypotheses of relationships between organisms during the vertebrate transition from water to land. This information also reveals exciting new data that can be used to gauge the evolution of senses (sight, smell, hearing) during this important period of vertebrate evolution.
