Soumen Ghosh is an Assistant Professor at the Department of Chemistry, IIT Madras, His research is mainly focused on the development of quantum mechanical electronic structure methods to model electron transfer processes, spectroscopic properties and noncovalent interactions in different chemical systems. During his PhD at University of Minnesota in the USA, he developed and applied different electronic structure methods to model charge and energy transfer processes in organic electronic materials. As an Alexander von Humboldt postdoctoral fellow at Max-Planck-Institute for Coal Research in Germany, he worked on the development of low scaling quantum chemical methods for excited states and noncovalent interactions. Later during his second postdoctoral stint at Pacific Northwest National Laboratory in the USA, he developed computational methods for modeling linear and nonlinear X-ray spectroscopic signals. In March 2023, he joined as an Assistant Professor in the Department of Chemistry at IIT Indore. He moved to IIT Madras in October 2023.
