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 over 100 publications that include peer-reviewed papers (88), 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.

Fabian is a visiting PhD student from Ulm University, Germany, under the supervision of Prof. Timo Jacob. At Ulm University, he works in the area of electrochemical metal deposition out of ionic liquids. To understand the fundamental processes which occur during the metal deposition on polycrystalline surfaces, knowledge from measurements on multiple oriented monocrystalline electrodes need to be obtained first. At Queen's University, he will be working alongside Derek Esau on the single crystal preparation technique and is looking forward to studying new surfaces through the usage of the scanning tunneling microscope (STM).
