Alexandre studied Chemistry at the University of Berne, where he obtained his M Sc in 2012 (summa cum laude). He conducted his Master’s thesis in the group of Prof. Martin Lochner, working on the synthesis of 2-aminoethyl diphenylborinate analogues for inhibiting TRPV6-mediated calcium transport. After a civil service stay at Agroscope near Sion, where he was involved in setting up and evaluating optimised irrigation techniques for apricot and apple trees, he joined the group of Prof. Henning Jessen for PhD studies at the University of Zurich. There, his main research focus was on developing novel phosphorylation strategies to enable the synthesis of nucleoside oligophosphates and other biologically relevant polyphosphorylated molecules in a highly modular way. He obtained his PhD in 2016 (with distinction and Legat Price from the Faculty of Science) and was awarded an SNSF Early Postdoc.Mobility Fellowship to work on methods to detect modified adenine DNA bases in the group of Prof. Sir Shankar Balasubramanian. Since mid-2018, he is the holder of a Marie Skłodowska-Curie Individual Fellowship.
