Noémi M. Nagy is a professor of radiochemistry in the Imre Lajos Isotope Laboratory of Physical Chemistry, University of Debrecen, Hungary. She earned her M.Sc. and Ph.D. degrees in radiochemistry at that university. She has a D.Sc. degree in agrochemistry from the Hungarian Academy of Sciences. Dr Nagy has more than 35 years of experience in nuclear and radiochemistry teaching. Her research interest is the study of the interfacial processes of natural sorbents, including soils, rocks, clay minerals mainly by radioactive tracer methods. Recently, she has been dealing principally with studies of nuclear waste storage. She has written or co-written numerous peer-reviewed scientific papers and is the co-author four books in the fields of nuclear and radiochemistry as well as the interfacial chemistry of geological formations. She won the George Hevesy’s award for nuclear safety in Hungary. Dr Nagy is the president of the Radiochemical Scientific Committee of Hungarian Academy of Sciences.
