My research is focused on unsteady fluid dynamics and fluid-structure interaction (FSI) where the motion of a structure or boundary influences the flow, which in turn moves or deforms the structure. This work involves computational fluid dynamics (CFD) simulation of moving boundary flows in laminar, transitional and turbulent regimes, and flow speeds ranging from subsonic to hypersonic. Applications are highly interdisciplinary, and include energy generation, conversion and storage engineering (energy harvesting from flapping foil water/wind turbines), zoology (flapping wing insect and bird flight), biomedical engineering (blood flow and blood vessel collapse), aerospace engineering (shock wave control and interaction with fixed and flexible structures), bioinspired design (flapping wing micro drones, noise reduction in turbines, machine learning for underwater vehicle control), and elite sports performance estimation and drag reduction (cycling and swimming).
