Assistant Professor of Chemistry, Ashoka University
Ph.D. CSIR-National Chemical Laboratory (CSIR-NCL), PuneAryya Ghosh is currently an Assistant professor of chemistry at Ashoka University. Before joining to Ashoka, he did his Ph.D. in theoretical and computational chemistry from the CSIR-national chemical laboratory (CSIR-NCL), Pune. He was a postdoctoral fellow at Emory university, USA as well as Heidelberg university, Germany. He was also a visiting research fellow at University of Edinburgh, UK. Prior to his doctoral studies, he did his Masters in physical chemistry from the central university of Visva-Bharati.
He is a theoretical chemist. His primary research  interests are mainly focused on the development and application of accurate ab initio methods to study the various interatomic or intermolecular decay processes of excited states and accurate multi-mode quantum dynamics simulation of  these decay processes using time dependent approach. Furthermore, his research interest is also focused on the exploration of new novel type photo-dissociation mechanism.
