Assistant Professor  

Dr. Bradley O. Christoffersen

I am a broadly trained ecologist, with extensive experience in tropical forests and soon the thornscrub ecosystems of the Rio Grande Valley. My research focuses on plant physiological ecology, ecosystem ecology, and models which scale up processes from plant tissues to whole ecosystems.
