Research in this thrust explores the effects of ecologically relevant conditions (e.g., surface roughness, substrate flexibility, salinity, temperature) on the biomechanics of adhesion, friction, and multiple modes of locomotion (e.g., running, jumping, ambulating). We also study similar topics in benthic station-holding fishes, such as marine sculpins, through collaborations. This thrust includes studies focused on biomechanical interactions between introduced and native species to better understand the role biomechanics plays in and how native species may be impacted by species introductions. 

Research in this thrust assays morphological and anatomical variation in animal locomotor and attachment systems to generate functional hypotheses for locomotion and attachment. Ongoing studies explore intra- and interspecific patterns of gecko claw morphology and sea urchin tube foot anatomy in relation to habitat use and/or locomotor strategies. Recent collaborations have resulted in the discovery of epidermal microstructures on the paired fins of marine sculpins, leading us to develop functional hypotheses related to benthic station-holding. 

Research in this thrust is focused on identifying the mechanical principles of animal attachment and locomotion. Ongoing work includes studies of how loading orientation influences the mechanics of sea urchin adhesion to rough substrates and visualization of contact mechanics of sea urchin tube feet during adhesion. Recently funded collaborative work from the Office of Naval Research is concentrated on further developing biologging tags that can maintain robust attachment underwater and weather repeated loading cycles on the dorsum of free-ranging marine mammals.
