Igor Kovalchuk, Ph.D., MD, is Professor and Board of Governors Research Chair at the Department of Biological Sciences, University of Lethbridge (Alberta, Canada). He edits Frontiers in Plant Microbe Interaction, Frontiers in Epigenomics, and other journals. As principal investigator in the university’s Plant Biotechnology laboratory, he studies genetic and epigenetic regulation of plant response to stress, including the transgenerational effects of stress and microevolution of plant stress tolerance/resistance.
Olga Kovalchuk, Ph.D., MD is Professor and Board of Governors Research Chair and CIHR Chair in Gender and Health at the University of Lethbridge and a member of the editorial boards of Mutation Research--Fundamental and Molecular Mechanisms of Mutagenesis and Environmental and Molecular Mutagenesis. She researches the role of epigenetic dysregulation in carcinogenesis; epigenetic regulation of cancer treatment responses; radiation epigenetics and role of epigenetic changes in genome stability and carcinogenesis; radiation-induced oncogenic signaling; and radiation-induced DNA damage, repair, and recombination.
