Research Projects/Interests

A fundamental question in biology is how structures match function to enable survivorship and fitness. Many animals move to disperse, eat, reproduce, and escape predators. Successful locomotion depends on coordinating and integrating a complex phenotype that is hierarchically arranged from the physics that govern movement (biomechanics) to foraging behavior and predator evasion. My lab works at the interface of evolution, ecology, and mechanics by studying animal performance and morphology.

Our goal is to understand how anatomical variation shapes organismal ecology and evolution. We use interdisciplinary methods spanning muscle physiology, anatomy, biomechanics and behavioral ecology. Our techniques include scanning electron microscopy (SEM), high-speed video in nature, and digital dissections (diceCT).

Our success depends on recruiting, retaining, and promoting a diverse and inclusive team of researchers. Only if our research reflects and includes our incredible student diversity will we make unique and innovative contributions in functional morphology. Therefore, I am fortunate to work at Sacramento State.
