MAJOR RESEARCH INTEREST: Biomechanics and Physiology of Bird Flight.

As a comparative biomechanist, I enjoy exploring questions that blend biology with physics.  My primary passion for science is for furthering understanding of the biology of bird flight.  I use a variety of techniques in the laboratory and in the field to measure wing motion, muscle contractile behavior, and aerodynamics with an overall goal of improving understanding of how flight shapes the ecology and evolution of birds and other flying animals.

Two key aspects of my research philosophy are that it is important to study biology both in the lab and in the field and, secondly, to maintain all questions within a comparative, phylogenetic context.  We enjoy ample space and equipment for lab research, including a variety of high-speed cameras, banks of physiology-recording equipment, two variable-speed wind tunnels, and a laser-based system for digital particle image velocimetry of airflow.  The phenomenal opportunities for field research in Montana and the outstanding aviary resources at the field station both make it easy to measure what animals are doing in the “real world” away from the artificial environment imposed within a laboratory.

As I have broad interests in form and function of organisms, it is important to note that I am open to collaborating on projects, serving as an advisor to graduate students, with inquiry into other aspects of animals and plants aside from flight. For example, I am fascinated by the mechanics and ecology of wood excavation in cavity nesting birds.  The principles of flow dynamics associated with flight are essentially the same as those for swimming, and this would open possibilities to supervise research involving locomotion in aquatic fish, reptiles and mammals.  Presently, I am collaborating with Dr. Art Woods, also of the Division of Biological Sciences, to measure flow characteristics in the boundary layers of leaves.

The Field Research Station at Fort Missoula is eager to host visiting scientists, so please contact me if you are interesting in working here during a sabbatical or other extended stay.
