Alexander L. Nielsen is a senior postdoctoral researcher in Professor Christian Heinis' lab at EPFL in Lausanne, Switzerland. His research interest revolves around high-throughput experimentation and the synthesis/screening of cyclic peptide libraries against challenging drug targets.

Alexander earned his Ph.D. from University of Copenhagen, 2021, where he worked on design, synthesis and pharmacological characterization of peptidic inhibitors against sirtuin enzymes. During his Ph.D., he was also awarded a Fulbright scholarship, which took him to Scripps Research in La Jolla, CA, to work on covalent inhibitors of Botulinum Neurotoxin with Professor Kim Janda. Outside of the laboratory, he enjoys spending time in the surrounding Swiss mountains.
