Dr Asok K Mukherjee has 40 years of teaching experience at the UG and PG levels. He retired as Professor of Chemistry from The University of Burdwan. He has published about 150 papers in international journals in the fields of theoretical chemistry, fullerene structure, spectra of CT and host–guest complexes, and photophysical sensors. He has supervised several research candidates and is presently interested in the applications of DFT.

Dr Bankim Chandra Ghosh is Assistant Professor of Chemistry, Durgapur Government College where he is teaching at both the UG and PG levels. His present area of research involves the study of photophysical properties of molecules with potential applications. He has published research papers in reputed international journals such as J. Phys. Chem. (A and B), Chem. Phys. Lett., J. Photochem. Photobiol. and J. Ind. Chem. Soc..
