Andreas graduated in Chemistry at the Philipps-University Marburg. He did his thesis on the synthesis and functionalization of gold nanoparticles with analyte-sensitive fluorophores in the group of Prof. Wolfgang Parak (Physics department, Philipps-University Marburg, Germany), where he first came in touch with nanotechnology. He then moved to the Italian Institute of Technology (Genoa, Italy) where he obtained his PhD in Nanoscience in the group of Prof. Liberato Manna and Dr. Teresa Pellegrino (Nanochemistry department). Central points of his dissertation were the synthesis und functionalization of magnetic, plasmonic and fluorescent nanocrystals with stimuli-responsive molecules and polymers, and the measurement of nanometric temperature profiles around magnetic nanocrystals under alternating magnetic field excitation. Later he joined the Optical Materials Engineering Laboratory of Prof. David J. Norris at the ETH Zürich (Switzerland) as a postdoctoral research fellow, working on the synthesis and doping of colloidal nanomaterials and on the formation mechanisms of quasi-2D nanocrystals. In 2017 he joined the MPI-P as group leader in the department of Prof. Katharina Landfester.
