I am a researcher at the University of New Mexico whose interests lie at the intersection of macroecology and macroevolution. My work focuses on understanding ecological patterns over space and time as a function of physiology and simple theory. To this end, I have focused on the role of energy as a means of linking ecological scales. Some of the questions that motivate me include: What are the energetics of extinct taxa, such as dinosaurs? How do differences in metabolic rates affect foraging, competition, community structure and biogeography? My study subjects range from trees to dinosaurs and everything in between.
