Marine Mammal Biomechanics
My PhD dissertation research focused on understanding potential injury risk from a tidal turbine hitting a marine mammal through marine mammal biomechanics. I performed laboratory experiments post-mortem on material properties of harbor seal, harbor porpoise, dall’s porpoise, and Southern Resident Killer Whale. I modeled these materials in Abaqus finite element analysis software to mimic laboratory material behavior.
