Research Interests:
________________________________________________________________
   
I am interested in all areas of herpetology. My main research interests are in            
 evolution, ecology and conservation of amphibians and reptiles. At heart I am          
 truely a "snake guy" and have a keen interest in the evolution and ecology of            
 venomous reptiles. I am particularly interested in phylogeny and the use of              
 phylogenies to answer questions about ecology and evolution. I try to                      
 incorporate multi-disciplinary approaches using phylogeny and GIS-based               
 methods to answer macro-evolutionary questions. I am currently a Master's             
 student and research assistant working under Dr. Laurie Vitt. In my thesis
 research I am investigating the spatial and temporal components that have             
  shaped South American reptile diversity. I am using a widely-distribued                  
  species, Corallus hortulanus, to test several biogeographic hypotheses.

Biography: I am what is
known as a born herper. From
my earliest childhood
memories I have been flipping
rocks, climbing trees and
chasing snakes and lizards.
After high school I took a
hiatus from my studies and
ran a successful
herpetoculture business that
supplied amphibians and
reptiles to zoos, universities
and private collectors all over
the world. While through this
experience I gained a great
deal of knowledge about
global herpetofauna, I knew
my true passion was in
science. I sold all of my
inventory and returned to
research.
