Gregory Jerkiewicz received his dual accreditation Master’s degree in Chemical Engineering-Engineering Chemistry from the Gdask University of Technology, Poland, in 1984. He also studied solid state physics at the same university (1983-1985). In 1985, he immigrated to Canada and settled down in Ottawa, where he completed his Doctorate (1991) at the University of Ottawa under the supervision of the late Prof. Brian E. Conway (FRSC), one of the icons of electrochemistry of the XX century. Following the doctoral studies, he spent the summer of 1991 working in the Institute of Physics, the University of Fribourg, Switzerland. He joined the Department of Chemistry, Université de Sherbrooke, as a research associate in September 1991 and became Assistant Professor in June 1992. He was promoted to Associate Professorship with tenure in June 1997. In 1997, he won the Electrochemistry Award of the Société Française de Chimie, the first time ever awarded to a researcher residing outside of France. In June 2002, he joined the Department of Chemistry, Queen's University, first as a tenured Associate Professor; he was promoted to the rank of Professor in 2005. In 2004, he was awarded the W. A. E. McBryde Medal of the Canadian Society for Chemistry in recognition of his contributions to interfacial electrochemistry and of his advancement of the electrochemical quartz-crystal nanobalance (EQCN). He has authored 154 publications that include peer-reviewed papers (120), peer-reviewed book chapters (6), papers in volumes of conference proceedings (24), editorials and prefaces (4), and has co-edited one (1) book and three volumes (3) of conference proceedings. He has delivered over 200 invited keynote lectures, seminars, and conference presentations, and over 260 contributed conference presentations. He has been an active member of several professional associations (the International Society of Electrochemistry, the Electrochemical Society, the Canadian Society for Chemistry) and has served on several executive committees (CSC, ECS – Canadian Section). He was Section Editor of the Canadian Journal of Chemistry and is Editor-in-Chief of Electrocatalysis published by Springer Nature. In 2012, the President of Poland, His excellency Bronislaw Komorowski, conferred on him the Knight’s Cross of the Order of Polonia Restituta in recognition of his outstanding contributions to the Polish society in the 1980s. In 2018, he was awarded the title of Professor of Chemical Sciences by the President of the Republic of Poland, His Excellency Andrzej Duda, in recognition of his outstanding and internationally renowned contributions to electrochemistry and electrocatalysis.  In 2018, he received the Eminent Visitor Award of the Catalysis Society of South Africa in recognition of his ground-breaking contributions to interfacial electrochemistry and electrocatalysis of platinum and platinum-based materials.  In 2022, he was awarded the Rio Tinto Award of the Canadian Society for Chemistry in recognition of his contributions to electrochemistry and electrocatalysis.  In 2022, the President of Poland, His Excellency Andrzej Duda bestowed on him a Cross of Freedom and Solidarity. In 2024, he was elected a Fellow of the Chemical Institute of Canada (FCIC).
