Executive Summary

Professor Rupamanjari Ghosh is a researcher, teacher, orator and an academic administrator par excellence. Professor Ghosh has B.Sc.(Physics honors) and M.Sc.(Physics) degrees from the University of Calcutta, and a very well-recognized Ph.D. from the University of Rochester, NY, where she worked as a Rush Rhees Fellow, chosen for "outstanding scholarly ability and the promise of exceptional contributions to scholarship and teaching." Her research interests are in Experimental and Theoretical Quantum Optics, Laser Physics, Nonlinear Optics, and Quantum Information. Her pioneering work with Prof. L. Mandel on two-photon interference (using the nonlinear optical process of spontaneous parametric down-conversion) has yielded a new direction in quantum optics and quantum information, in the creation and use of a source of entangled photon pairs, and of single photons, at the forefront of research today.

Professor Ghosh is a former Dean, School of Physical Sciences at Jawaharlal Nehru University, New Delhi, where she had held many other important academic and administrative positions. She has held several Visiting Faculty / Scientist positions on invitation abroad, and delivered numerous invited research seminars in India and abroad. Recipient of the Stree Shakti Science Samman for her “original contribution to Science”, she serves as an expert in crucial DST (Government of India) committees in Physical Sciences, and in many Central and State universities and institutes. She has also served as the Chief Advisor for the National Council of Educational Research and Training (NCERT) Science textbooks for Classes IX and X, developed afresh under the National Curriculum Framework-2005.

Besides her contribution to science research and training from the university to the school level, she is also well known for her stand and efforts to bring in gender justice and environment consciousness in the higher education system.

She joined the Shiv Nadar University in 2012 as the Founding Director of the School of Natural Sciences, with a glowing reference from a Nobel Laureate, and she shaped the vision and mission of the School, which has started drawing attention of the world community in this very short period of time. She also took charge as the Dean of Research & Graduate Studies, the Head of the Faculty Development Center, and more recently, as the Director of the School of Engineering. She has taken over as the Vice-Chancellor of Shiv Nadar University from 1 February 2016.
