Research and academic interests: 

My research interests involve examining trade-offs in behavioral, mechanical, and physiological performance of animals in their natural environment. I am especially interested in how compromises in various traits related to conflicting physical, behavioral, and/or ecological demands influence both performance and an animals' evolutionary history. Past and current projects have focused on the following areas:

  1. Trade-offs in locomotor performance among disparate modes of limbless locomotion in lizards and snakes
  2. Influence of limb size on locomotor performance and kinematics in lizards
  3. The role of salinity selection on predator avoidance behaviors and aquaporin expression in euryhaline fishes
  4. Influence of abiotic factors on anti-predator behavioral strategies in reptiles
  5. How shell morphology and temperature affect burrowing and anchoring performance in freshwater mussels
  6. Influence of the sexually-selected enlarged claw in male fiddler crabs on locomotor abilities
