His research interests include Large-Eddy Simulations (LES) embedded in CFD software for flow, pollutant dispersion and heat transfer in urban environments; coupling between large-scale geophysical flow and small scale turbulent flow. His recent studies include efficient turbulence inflow generation techniques for LES, which has been incorporated in commercial CFD software releases (e.g. Star-CD v4), and adopted by leading design and engineering firms, and used by researchers in academia all over the world.
