Phylogenetics Systematics and Evolution of Fishes and Mussels

My research in the area of phylogenetic systematics has involved using DNA sequence data to improve our understanding of the evolutionary relationships of organisms.  Phylogenetic hypotheses provide a framework to address questions as diverse as species delineation, biogeography, and character evolution.

Past research projects on the Centrarchidae and the Petromyzontiformes have been sponsored by the National Science Foundation. Topics of more recent research includes freshwater shrimps in the family Atyidae and freshwater mussels in the genus Ptychobranchus.mt phylogeny of freshwater mussel genus Ptychobranchus.

Research Proposal Funded

The proposal: Habitat Improvement Projects for Stream and Oxbow Fish of Greatest Conservation Need, that was submitted as a Competitive State Wildlife Grant (SWGc) was funded. The project involves a collaboration with several state and federal agencies as well as two other NREM faculty members (Clay Pierce and Mike Weber).  An overview of the project is below.
