Bernd Wollscheid is a Professor for Chemical and Systems Biology at the Swiss Federal Institute of Technology in Zürich, Switzerland. After studying chemistry in Freiburg and Boston he obtained his PhD in Molecular Immunology from the Max-Planck Institute for Immunobiology. His postdoctoral research took him to the Institute of Systems Biology in Seattle where he developed and applied chemoproteomic technologies to elucidate cell surface protein biology. As a group leader and PI at the Institute for Molecular Systems Biology at ETH Zurich he developed a research program focusing on a systems biology understanding of the cell surface as a cellular information gateway and on the identification of cell surface glycoproteins as diagnostic and therapeutic clinical targets. Now at the Department of Health Sciences and Technology of ETH his team developed and applied chemoproteomic technologies which enable the decoding of the extracellular interactome.
