Research Interests:

I am broadly interested in the physiological ecology and biomechanics of marine organisms, especially squids and boxfishes. I am particularly intrigued with how these organisms generate propulsive and stabilizing forces, maneuver, and sense hydrodynamic perturbations within their respective environments. Squids are remarkably diverse swimmers that use their mantle, funnel, fins, and arms for locomotion to varying degrees depending on life history stage and species. I am interested in studying the interplay of movements of these body features to understand how these organisms move and compete with ecologically relevant nekton. The locomotive physiology of boxfishes is another strong interest of mine. My colleagues and I are just beginning to uncover the complexity with which boxfishes maneuver and maintain smooth swimming trajectories within highly turbulent reef environments. Interactions between body-induced flows, which are very important for hydrodynamic stability, and fin movements appear to play an important role in swimming and may provide useful insights into the maneuverability of rigid-bodied swimmers. Finally, I am beginning to explore how squids and fishes produce and detect hydrodynamic perturbations within their respective environments. I use a variety of techniques in my research, such as swim tunnel respirometry, planar and volumetric (defocusing) digital particle image velocimetry, electromyography, pressure/force transducers, and high-speed videography. These techniques are used to link movements of locomotor structures with their momentum consequences and reconstruct spatial and temporal dynamics in unsteady aquatic locomotion.
