Mark Herr Researcher Email: mwh5426@psu.edu Research Interests I have a tremendous interest in tetrapod zoology, particularly the ecology, behavior, biogeography, and evolution of mammals, reptiles and amphibians. I also have some interest in venom systems in general, and the medical significance of snakebite in particular. I hope to pursue a future in research, and would like to contribute to both the body of knowledge and the conservation of these animals.
