Dr. Sumita Datta

Associate Professor

Alliance School of Applied Mathematics

Dr. Sumita Datta holds a Ph.D. in Physics from The University of Texas at Arlington, USA and an M.Sc.  In Physics from Indian Institute of Technology, Kharagpur. With 25 years of experience in teaching and research in reputed institutions in India and abroad, Dr. Datta has more than 23 publications in international journals of repute. She started her research career in ISRO, Bangalore wherein she was involved in a project in Space Physics. She has done numerous governments funded research projects in her career as a Principal Investigator in institutes like Indian Association of Cultivation of Sciences, Kolkata, S N Bose National Centre for basic Sciences, Kolkata to name a few.

Over the last 25 years she has taught several courses in Physics, Mathematics and Engineering Sciences in different esteemed institutes. The key theme of her research is related to quantum many body physics and nonlinear dynamics. Her endeavour has throughout been supported by Department of Science and Technology, New Delhi and Council of Scientific and Industrial Research (CSIR), New Delhi through several major research grants. Currently Dr. Sumita is involved in research projects intimately connected to soliton physics and strongly correlated systems. She has a passion for delivering invited and contributed talks, seminars at various international and national conferences and symposiums.
