Research Interests

My research centers on computational fluid dynamics, spanning a diverse and cross-disciplinary range of topics in biofluids, hydraulics, environmental fluid mechanics, chaotic advection, and large-scale transport in geophysical flows. A major thrust of my research is the development of advanced numerical algorithms for simulating turbulent flows in real-life natural and man-made environments using statistical turbulence models that directly resolve the dynamics of unsteady, coherent structures. These algorithms are applied to simulate sediment transport by large-scale vortices in the vicinity of bridge foundations, turbulent flows in hydraulic machinery, stratified and buoyancy dominated flows in lakes and reservoirs, and turbulent mixing in water and wastewater treatment mixing devices and in water storage facilities. My research group also developed a novel computational technique for simulating flows in domains with 3D, arbitrarily complex, flexible immersed boundaries. This technique is being used to tackle computationally problems that reside at the interface between fluid mechanics with biology and bioengineering. Projects include the simulation of various cardiovascular flows, with emphasis on biomedical devices and virtual surgery, hydrodynamics of aquatic locomotion, and hydrodynamic signal detection by planktonic organisms. Another area of research is the experimental and computational investigation of Lagrangian coherent structure dynamics in chaotically advected flows as well as in large scale geophysical and environmental flows.
