Karol Grela, F CSPE was born in Warsaw, Poland in 1970. He received a Master degree from Warsaw University of Technology in 1994, and received his PhD degree from the Institute of Organic Chemistry, Polish Academy of Sciences, in 1998. As Alexader von Humboldt Scholar, he spent one year in the Max-Planck-Institut für Kohlenforschung, Mülheim an der Ruhr, Germany, just in time to be present at the blooming of metathesis methodology in the laboratories of Professor Alois Fürstner. Next, he returned to Warsaw, and after completing his Habilitation in 2003, at the Institute of Organic Chemistry, Polish Academy of Sciences where he led a small but very efficient research group of dedicated co-workers. In 2008 he was promoted to Full Professor. Since 2008, he is also a Director of newly formed group at the Biological and Chemical Research Centre of the Faculty of Chemistry, University of Warsaw. His synthetic research focuses on improving synthetic efficiency of organic reactions, organometallic chemistry and catalysis. His work with metals involves the development of new catalysts and conditions for alkene and alkyne metathesis. Prof. Grela was awarded some prizes including the Alexander von Humboldt Fellowship (1999), Maria Curie and Wilhelm Klemm Lectureship of the German Chemical Society (2007), Prime Minister of Polish Government Prizes (1999, 2004 & 2010), the Prize of Foundation for Polish Science (2014) and French Chemical Society Prize (2016). He is the member of Editorial boards of Chemistry–A European Journal, European Journal of Organic Chemistry, ChemSelect, and a fellow of ChemPubSoc Europe.
