Research

The biodiverse tropical regions of the world provide rich sources of natural variation in organism function that can profitably be examined using modern molecular genetic approaches. To understand the history of animal diversification in the tropics, I reconstruct evolutionary relationships among taxa using molecular phylogenetics. The resultant phylogenies provide insight on the history of speciation, and the role of geographic connections and barriers in promoting diversification (biogeography). I am also interested in the molecular evolution of genes with important ecological and behavioural functions. My lab is currently examining ion channel genes that play a role in the production of electric signals in Neotropical electric fishes (Gymnotiformes). By correlating differences in electric signal parameters with genetic variation, we hope to gain insight into the evolutionary processes that affect organism function. We are also examining the molecular consequences of marine to freshwater habitat shifts in a variety of fishes that have invaded tropical rivers like the Amazon. My research integrates fieldwork and molecular lab approaches, and many of my students have combined these two aspects in their research projects.
