Research Statement

Research in my lab aims to understand the evolutionary sequence of events involved in major vertebrate transitions, especially aspects of the evolution of the cardiopulmonary system and the transition from ectothermy to endothermy. We combine historical data with neontological studies and, occasionally, mathematical models to piece together scenarios for the acquisition of key vertebrate features.

Research Interests

General Interests
Specific Interests
  • Vertebrate evolutionary physiology and functional morphology
