Dr. Das received his B.Sc. degree from Vidyasagar University, Medinipur (W.B.) and M.Sc. degree from Banaras Hindu University, Varanasi (U.P.). He completed his Ph.D. in December 2010 under the supervision of Prof. Puspendu K. Das and Prof. E. Arunan at the Indian Institute of Science, Bangalore where his research interests include the infrared spectroscopic studies of Polycyclic Aromatic Hydrocarbons (PAHs) and Diols in the gas phase. He was a postdoctoral research fellow with Prof. Yuan-Pern Lee at the National Chiao Tung University, Taiwan with research interests on the identification of transient chemical species using para-hydrogen matrix isolation (p-H2, 3.2 K) infrared spectroscopy. Subsequently, he has spent six months at IISc Bangalore as a research associate to develop Time-Resolved Step-Scan FT-IR spectroscopy for solution phase reaction dynamics. Then, he moved to the University of Alberta, Canada, where he worked on helium nanodroplet isolation (0.38 K) laser spectroscopy of molecules, molecular complexes, and transient chemical species with Prof. Wolfgang Jäger. In 2018, he was appointed as an Assistant Professor at Institute of Engineering & Rural Technology Allahabad where he developed Engineering Chemistry lab. Since 2021, he moved to Ganpat University as a senior Assistant Professor.

He was selected for prestigious Alexander von Humboldt (Germany) postdoctoral research fellowship in 2015 and awarded for the best poster presentation in 2013. He also awarded with Lectureship in NET and GATE (AIR 62) in 2004, etc.

Field(s) of specialization: Physical Chemistry, Spectroscopy, Low Temperature Optical Techniques, Reaction Dynamics, Photochemistry, Pyrolysis, Drug Degradation, Molecular Biology, Atmospheric Chemistry.
