PATENTIntroduction [Biosketch]
- Dr. Saumya R. Mohapatra is an Associate Professor of Physics and currently serves as the Head of the Department. He joined the institute in 2014 as an Assistant Professor. Dr. Mohapatra earned his Ph.D. in Physics from the Indian Institute of Technology (IIT) Kharagpur in 2009. He subsequently held postdoctoral research positions at the National Institute for Materials Science (NIMS), Japan (2010–2013), and Ibaraki University, Japan (2009-2010).
- Dr. Mohapatra’s research focuses on ion-conducting materials for energy storage and conversion devices, including batteries, fuel cells, and supercapacitors, as well as iontronic devices such as redox-based memristors and ionic PN diodes. His current work emphasizes on understanding and controlling ion dynamics in polymers, oxides, and 2D materials to develop diffusive and analog memristors. Leveraging their nonlinearity, tunable conductance, and biosimilar memory, his group explores novel computing paradigms like ANN hardware and physical reservoir computing. He has authored 36 research publications, including peer-reviewed journal articles, conference proceedings, and book chapters; and holds a German Utility Patent. Dr. Mohapatra has successfully supervised two Ph.D. scholars and over 20 M.Sc. students in their dissertation projects.
- In addition to research, Dr. Mohapatra is actively involved in teaching and learning. His academic interests include condensed matter physics, semiconductor physics, atomic and molecular physics, and experimental techniques at both M.Sc. and advanced level. He also enjoys teaching undergraduate physics courses, including the laboratory.
