My interest in biology has taken me from the bottom of the Grand Canyon to remote fishing camps in Baja, and my study organisms have come from both the plant and animal kingdoms.  My scientific interests include ecology, physiology, biochemistry, biomechanics, and functional morphology.  Currently, my study organisms of choice are elasmobranchs (sharks, skates, and rays).  I am interested in two features of these animals; their cartilaginous “backbones” and the holes (spiracles) found in the heads of some species.  Please peruse this site for more information on my research.  Thanks for checking out my site.
