Jakub Drozak completed his Master's studies in Biotechnology at the Faculty of Biology, University of Warsaw (1997-2002). Then he received the PhD degree (2006) based on a PhD thesis concerning a hypoglycemic action of antiparkinsonian drugs: L-DOPA and selegiline, supervised by Professor Jadwiga Bryla. In 2008, he joined the research group of Professor Emile Van Schaftingen and Dr. Maria Veiga-da-Cunha at de Duve Institute (Belgium) to be trained in modern enzymology. After returning to Poland, he received the assistant professor's position and established the enzymology group in the Department of Metabolic Regulation, University of Warsaw. He then began new projects in the field of enzymology and, in 2016, was awarded a D.Sc. degree (habilitation). His current research focuses on the molecular characterization of orphan enzymes, particularly metabolic enzymes and those responsible for posttranslational modifications.
