My main research interest has been to cross-fertilize skills and ideas across the disciplines of numerical analysis, hydraulic engineering, and computational sciences, to address frontier issues in modelling of hydrodynamics for water resource and environmental problems.
From a background in Mathematics I switched to water engineering since my PhD study (2005-2008) at ENGEES (National School for Water and Environmental Engineering). During PhD, I developed new scientific formulations for modelling 1D/2D water flows through urban channel networks. I also entered into a multidisciplinary collaboration with researchers at Lyon University (Prof Rivière) to validate these model formulations against experiments and 3D computations.
In Oct. 2008, I moved to Newcastle University (UK) to commence post-doctoral research with Prof Liang (EP/F030177/1), and in close involvement with the Flood Risk Management Research Consortium (EP/F020511/1). Since then, I have focused on tackling outstanding challenges in flood modelling research, by harnessing the latest cross-disciplinary advances (incl. multiscale analysis, discontinuous Galerkin method, adaptive meshing techniques, efficiency speedup algorithms, etc.).
In Aug. 2011, I took up a lectureship at Sheffield, joining their international Water and Fluid Mechanics Groups. Here, I have developed new partnerships and broader activities spanning fundamental, experimental and applied research, with a vision to improve our sustainable living with water and environmental change.
