RESEARCH


My research interests center on the development and application of computational techniques for problems in fluid mechanics, including aerodynamics of insect flight, flow control, supersonic and hypersonic turbulence, and two-fluid flows. I am also interested in the development of thermal energy and energy harvesting techniques.


The immersed interface method (IIM): [PPT] My current research focues on the development of the immersed interface method (IIM) for fluid-solid interaction and two-fluid flows. This research is supported by the NSF grant DMS #0915237.



Aerodynamics of insect flight: I am collaborating with Professor Jane Wang [LINK] to investigate aerodynamics of insect flight, including flight efficiency, stability, and control.
