My primary research interests are invertebrate phylogeny and phylogeography. I am primarily interested in the extremes of the molluscan and annelidan radiations. While most mollusks are rather sedentary aquatic animals, some (cephalopods) are active, swimming predators with an array of spectacular ...read full profile >>

Much of my basic research focuses on the optimal expression of body temperature (i.e. thermoregulation) under varying ecological conditions as well as the evolutionary history that has led to the patterns of thermoregulation we see today. I use a multitude of approaches including non-manipulative ...read full profile >>

Many investigators have assumed that the bioenergetics of ectotherms respond similarly to conditions along environmental gradients. My colleagues and I have been challenging this view, finding that energetic adaptations can influence growth and behavior of fish along broad latitudinal gradients. ...read full profile >>
