India

Professor in Physics: expertise in scientific research, article publishing, data analysis, teaching, project supervision

プロフィール概要

I am working as a professor in Physics with about 15 years of research experiences in areas like condensed matter physics, nanotechnology, microelectronics, magnetism, nano electronics, spintronics, neutron and muon scattering techniques, thin film systems, device physics, numerical simulation, material characterisation, density functional theory calculations etc. I compiled my PhD from University of St. Andrews (UK) and worked at CEA Grenoble (France), TU Darmstadt (Germany) as a research scientist thereafter. During this period, I worked at several university labs and research facilities in Oxford, Manchester, Leeds (UK), Zurich (Switzerland) with collaboration from industry (Hitachi, USA). I have extensive experience of independent project management, successful external research grant application, student supervision, teaching, article publications and anything that is related to high-level research. I have published articles in high impact journals like Physical Review Letters, Physical Review X, Carbon etc, been on the proposal review panels, journal editorial board member and section editor. I have worked as a reviewer of more than 20 journals from reputed publishing houses like Elsevier, Springer, Nature group, IOP, ACS etc and various conferences around the world. The recent research direction includes renewable energy, bioelectronics, energy storage and sustainability, energy efficient architectures like neuromorphic computing, memory circuit design etc. Let me know if I can be of any help !
