Som is originally from India, and after completing his graduate studies at University of Illinois (UIUC) in Civil Engineering; he did his post-doctoral training in Scientific Computing and Mathematics at UIUC and City University of New York (CUNY), respectively. Som is interested in studying complex flow and morphodynamics phenomena in the natural and the built environment using high-fidelity computational fluid dynamic (CFD) models that often require the use of large-scale HPC platforms. Some of the diverse range of phenomena he is interested are predicting aerial fire-retardant dispersal; exploring the mechanism underlying drag reduction by shark denticles (skin); dispersal of oil and contaminant in oceans, rivers and lakes; fundamental dynamics of moving bodies in stratified environments; and transmission of airborne pathogens through aerosols.
