I am interested in many aspects of reproduction in amphibians, especially in salamanders (e.g., Plethodon and Desmognathus). My main focus is on male courtship pheromones, chemical signals that affect female receptivity. We have identified individual components of the pheromone and have shown that these components affect female responsiveness. We have also developed an expression system for one of the pheromone components (PRF, plethodontid receptivity factor) that successfully produces biologically-active, recombinant-PRF.
