Bijan Bagchi received his B.Sc., M.Sc., and Ph.D. degrees from the University of Calcutta. After Ph.D. he joined as an associate at the Raychaudhuri lab of Presidency College, Calcutta. Subsequently he went to the Institute for Theoretical Physics, University of Bern, Switzerland as a visiting scientist. A former Professor with the University of Calcutta he has served as its Head of the Department and also as the Coordinator of the UGC Special Assistance Programme. He later became a UGC Emeritus Fellow in the Department of Physics, Shiv Nadar University where he is currently holding the post of a Professor. Dr. Bagchi has held several research positions in Europe and the US including Visiting Professorships at Physique Nucleaire Theorique et Physique Mathematique, University of Libre, Brussels and also at Laboratoire de Physique et Chimie Theoriques, University of Lorraine, Metz, France and National Cheng Kung University, Tainan. During the past few years his research has focused in developing models for branched Hamiltonians, analysing group theoretic approach for rationally extended shape invariant potentials, carrying out a systematic quantitative study of generalised oscillators by casting them as model for dynamical systems and inquiring into the role of bi-complex Hamiltonians in quantum mechanics. He has published more than 150 research articles in various international and national journals in the area of theoretical physics and is the author of the books entitled Supersymmetry in Quantum and Classical Mechanics, Advanced Classical Mechanics and Partial Differential Equations for Mathematical Physicists, all published by the CRC Press, UK, respectively in the years 2000, 2017 and 2019.
