Michael Ojovan joined the Department in 2002 having previously worked more than 20 years at The Moscow Scientific and Industrial Association "Radon", the leading radioactive waste research institution of Russian Federation. He is a Fellow of Russian Academy of Natural Sciences and a Technical Expert of the International Atomic Energy Agency. He is noted for his work on metal matrix immobilisation, powder metal fuels, self-sustaining vitrification, glass composite materials, study of long-term behavior of cementitious, bituminous and glassy wasteforms, glass transition and viscosity of amorphous materials. He has published over 280 peer reviewed scientific papers, 5 book chapters, 14 IAEA documents and has 42 patents. He has published 6 books on nuclear materials including "An introduction to nuclear waste immobilization" by Elsevier 2005.
Research interests
Main research activities are now involved with:
