Saptarshi received his B.Sc. (Honours) degree in Chemistry from R K Mission Residential College, Narendrapur, India, in 2014. He then joined Indian Institute of Science Education and Research (IISER) - Kolkata as an Integrated Ph.D. student. After finishing his M.S. Thesis entitled – “Understanding Optical Behaviour of CsPbBr 3 Perovskite Quantum Dot”, he joined the group of Prof. Prasun K. Mandal for Doctoral research during August 2016. During Ph.D. tenure, Saptarshi has worked with all-inorganic Perovskites, II-VI (CdSe based) and III-V (InP based) semiconductor nanomaterials, however, the primary goal was focused in understanding the fundamental photophysical processes in these materials at the ensemble as well as single particle level. Saptarshi has more than five years of research experience in nanomaterial synthesis, elemental & structural characterization, photo-physics, and advanced laser spectroscopy and microscopy (TIRF, Confocal) with specialization in single particle spectroscopy & ultrafast pump-probe transient absorption spectroscopy technique. Saptarshi submitted & defended his Thesis entitled - “Exploring Optical Behaviour of All Inorganic Perovskite Nanocrystals through Ultrasensitive Single Particle Spectroscopy and Ultrafast Dynamics.” during February, 2022. He is currently a postdoctoral researcher in the group of Prof. Gordon Hedley within “Hedley Single Molecule Laboratory” at University of Glasgow, UK.
