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:
- Trade-offs in locomotor performance among disparate modes of limbless locomotion in lizards and snakes
- Influence of leg autotomy on locomotion in invertebrates
- Influence of abiotic factors on anti-predator behavioral strategies in reptiles
