Sushil K. Misra received his Ph. D. degree in Physics from St. Louis University, St. Louis, Missouri, USA in the area of condensed matter physics. He did his post-doctoral work at the University of Toronto. His current research interests are in both theoretical and experimental EPR (electron paramagnetic  resonance, also known as ESR, electron spin resonance). His research laboratory includes X-band (~9.5 GHz) and Q-band (~35 GHz) CW (continuous wave) EPR spectrometers, operational in the 4.2 – 1000 K temperature range.

He is carrying out experimental EPR research in functional materials in nano-state, e.g. dilute magnetic semiconductors, high-Tc superconductors, materials with applications to spintronics. He is also involved in theoretical pulsed electron spin-lattice relaxation studies using Stochastic Liouville and Liouville von-Neumann Equations, with the latest research being on   exploitation of pulse EPR technique to study electron spin-lattice (T1), electron- electron (T2), and nuclear spin relaxation (T2n) times in solids and liquids. Ten Ph. D. and the same number of Master’s students have received their degrees under his supervision. As well, some eleven post-doctoral students have collaborated on research under his supervision.

He collaborates actively with researchers at ACERT (Advanced Center for Electron Spin Resonance Technology) at Cornell University, Ithaca, NY, USA, whose director is the leading expert in EPR Professor Jack Freed, as a collaborating faculty member from Canada. Apart from single-crystal and polycrystalline Continuous Wave EPR research using the 170 and 240 GHz at ACERT, he does simulations for rigorous computations of signals obtained (i) by DQC (double quantum coherence) pulsed EPR to measure distances in membranes, and (ii) by 2D-ELDOR (two dimensional electron double resonance) pulsed EPR to measure distances in biological samples at  ambient  temperatures.

He has served as an external examiner to numerous international Ph. D. theses  outside of Concordia University, submitted in Canada, France, India, and Australia. He serves as a referee to important journals in Physics and Chemistry, publishing EPR research, e.g. the Physical Review and Physical Review Letters, Journal of Physics and Chemistry of Solids, Journal of Chemical Physics, Journal of Physical Chemistry, Journal of Magnetism and Magnetic Materials, Journal of Magnetic Resonance, Journal of Applied Magnetic Resonance. He has published several review articles in EPR, as well as he has written book chapters in leading research monographs. In addition, he has edited, and written chapters, in two books on Multifrquency EPR (Theory and Application & Data and Techniques). His research has been continuously supported by NSERC (Natural Sciences and Engineering Research Council of Canada) over 50 years. Of ther 290 papers published by him in peer-reviewed journals, over 250 are in the field of  EPR.
