Oleg M. Demchuk graduated from the Ivan Franko National University of Lviv (Ukraine) and earned his Ph.D. in Organic Chemistry from the Institute of Organic Chemistry of the Polish Academy of Sciences. He accomplished a postdoctoral NATO Science Fellowship at Queen’s University (Canada) was part of a program on the commercialization of science's "Top 500 Innovators" at Stanford University. He was hired as an Assistant Professor at Maria Curie-Skłodowska University in Lublin, a Professor at the Pharmaceutical Research Institute in Warsaw, and is currently a Professor at the Research Laboratory of Modern Chemical Synthesis and Technology of Pharmaceutically Active Compounds in the Faculty of Medicine, John Paul II Catholic University of Lublin. He was a member of IUPAC as a YO, and after that, he worked as an NR, AM, TM, and secretary in Division III and the CHEMRAWN Committee. His research interests embrace (in a wide sense) the exploration of asymmetric catalysis; the synthesis and practical application of biologically active compounds; supramolecular, heteroatom, and coordination chemistry; as well as the application of the transition metals in homogeneous catalyses. He also has an interest in the philosophy of chemical education as well as in the popularization of chemistry among young people.
