Bidyendu Mohan Deb

Bidyendu Mohan Deb (born 27 September 1942) is an Indian theoretical chemist, chemical physicist and a professor at the Indian Institute of Science Education and Research, Kolkata (IISER). He is known for his studies in theoretical chemistry and chemical physics. He is part of the International Union of Pure and Applied Chemistry, The World Academy of Sciences, Indian National Science Academy and the Indian Academy of Sciences.

In 1981, the Council of Scientific and Industrial Research awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology for his contributions to chemical sciences.

Early life and education Bidyendu Deb was born on 27 September 1942 in Bengal province in British India. He obtained his Honours BSc in Chemistry from the Presidency College in Kolkata (now Presidency University) and completed his master's degree in physical chemistry at the Rajabazar Science College (now the University College of Science, Technology and Agriculture).

Subsequently, he joined S. R. Palit at the Indian Association for the Cultivation of Science (IACS) for a year, before moving to the University of Oxford's Mathematical Institute. There, he completed a Diploma in Advanced Mathematics on a Commonwealth scholarship. Continuing at Oxford, he completed his doctoral research under the supervision of Charles Coulson, obtaining a DPhil in mathematics. as an INSA Senior Scientist and Honorary Scholar-in-Residence at Visva-Bharati University.

Legacy

Deb's main contributions are in the field of theoretical chemistry and the molecular geometry model he developed to demonstrate the influence of electronuclear attractive force and one of the highest occupied molecular orbitals in the determination of molecular shapes. His work on the applicability of the concept of internal stresses of molecules and solids revealed their relation to the density-functional theory and quantum fluid dynamics. He developed methodologies for predicting new molecules using quantum chemistry and for combining cellular automata with Thomas-Fermi-Dirac theory. He emphasized the general interpretative aspects of the electron density in chemistry. For both these ends, he concentrated on developing a single time-dependent equation (the Deb-Chattaraj or DC equation) for the direct calculation of electron density, which is different from the usual density functional theory.

His research have been published in peer-reviewed academic journals and he has authored two books, The Force Concept in Chemistry and The Single-Particle Density in Physics and Chemistry. He has also written about holistic education as well as on Satyajit Ray, one of the pioneers of modern Indian cinema. He was also involved with curriculum designing programs and seminars and has been associated with science journals as a member of their editorial boards.

In 2015, he published the book "The peacock in splendour: Science, literature and arts in ancient and medieval India" which focuses on Indology. Awards and honors
