Research

NAA

My research interests are in the musculoskeletal design of organisms, particularly how it relates to locomotion and posture. When I see an animal perform a particular behavior, I ask "how is it that this movement is possible?" and "how did this type of structural/functional system evolve?" To answer these types of questions, I currently employ a variety of techniques. First, an understanding of the structural basis of the system is essential. Thus I am very interested in dissecting animals to learn their anatomy. There are still tremendous gaps in our knowledge of even the most basic anatomical systems of animals. Second, we can analyze muscle function by removing a small sample and assaying it for a variety of enzymatic properties related to its function. Thus we can determine if a muscle is aerobic and specialized for a sustained, fatigue-resistent behavior, or anaerobic and better for short-duration but high-power effects.  

Past student projects have examined the wing-drying posture of cormorants, the postural muscles in gliding gulls and soaring albatrosses, and a study of pouch anatomy and biomechanics during diving in Brown Pelicans. Recent projects involving students include hindlimb flight posture in birds, an analysis of the muscle fiber characteristics in the syringeal muscles of songbirds, soaring flight biomechanics in Golden Eagles, and the hindlimb muscles of kangaroo rats. Many undergraduate students have presented their work at professional meetings.
