Gisbert Schneider is full professor of computer-assisted drug design at ETH Zürich, Switzerland. He studied biochemistry and computer science at the Free University of Berlin, Germany. After several international postdoctoral research activities he joined F. Hoffmann-La Roche Pharmaceuticals in Basel, Switzerland, where he headed the cheminformatics group. From 2002-2009 he was full professor of cheminformatics and bioinformatics (Beilstein Endowed Chair) at Goethe-University Frankfurt, Germany. Professor Schneider coined the terms ‘scaffold-hopping’ and ‘frequent hitter’ in drug design. His research activities concentrate on method development for adaptive molecular design and their tight integration with innovative chemical and biophysical techniques in drug discovery.
