Satyesh Chandra Prakashi obtained his Ph.D. degree from the University of Kolkata in 1954. He worked on the structures of tetraphyllicin, ajmalidine. He synthesized C14 incorporated Benz (a) pyrene, a well known carcinogen, and studied the application of its metabolites. His significant work was on the structure elucidation of the Rauwolfia alkaloid-yohimbine being the basis of the stereo-chemical assignment of the well known tranquilizing drug, reserpine. He pioneered in application of physical methods, such as mass spectrometry, for the structure elucidation of minor alkaloids. He served as the Director, IICB, Kolkata. He was the Founder President of Professor Asima Chatterjee Foundation of Kolkata. Dr. Prakashi was the recipient of the Basudev Memorial Award of the Indian Chemical Society, Kolkata, in 1967.

Amar Nath Maitra obtained his Ph.D. degree from the Jadavpur University, Kolkata, in 1971. His area of research was the structure and kinetics of microemulsions. He worked on nanomaterials, mainly gamma ferric oxides, barium ferrite nanocrystals, silver halides, etc. His significant research contribution was on polymeric and inorganic nanoparticles for drug delivery and gene delivery. He has six patents in his name. He was a visiting Professor at the University of Lund; the University of Basel, and Florida; Honorary Advisor for the MTech Course on Nanoscience and Nanotechnology at the University of Delhi.
