Academic and Research Contributions: The research work of Dr Ghosh has been in the areas of theoretical chemistry, soft condensed matter physics and computational materials science. He has contributed to the formulation of quantum chemistry in three-dimensional space using single-particle density quantities as basic variables; developed density functional theory (DFT) for time-dependent many-electron systems involving arbitrary electric and magnetic fields, and provided simpler routes to the direct calculation of electron density and response properties. He has generalized the concepts of electronegativity and chemical hardness, providing a new unified formulation for describing both covalent and ionic binding in molecular systems. He developed a thermodynamic picture of the electron cloud strengthening the foundation of several important chemical concepts that lead to better understanding of chemical reactivity. His work on the DFT of macroscopic systems covers the structure of soft matter under confinement at interfaces and pores, solvation forces, and ordering in colloidal suspensions. He has also contributed towards a new mode coupling theory and universal scaling laws for diffusivity in fluid mixtures; dynamics of flexible polymer chains; fluid flow through nanotubes, nucleation phenomena etc. Currently he has been involved in the computational design of materials for hydrogen energy applications involving hydrogen storage as well as generation through water splitting. His work has provided a single unified framework for theoretical description of many-particle systems (quantum as well as classical) within a single-particle picture, thus broadening the applicability of the density concept to the domain of multiscale materials modelling (microscopic, mesoscopic and macroscopic length scales). He has mentored a number of students including several PhDs.
