  • Research

    My research is in the broad area of computational fluid dynamics focussing on the development of novel computational frameworks for fluid flows, both in the compressible and incompressible regimes. My current research is targeted at devising immersed boundary/finite volume frameworks and its application to multi-physics problems. I am also interested in mathematical modelling in sports with an emphasis on cricket.
