Volker Schellenberger, Ph.D., CEO


Dr. Volker Schellenberger is a co-founder of Amunix and currently serves as President and CEO. Dr. Schellenberger has extensive industry experience in protein engineering and drug discovery. Previously, he headed the Protein Engineering department at Genencor, where he invented combinatorial consensus mutagenesis, selection by micro-compartmentalization, as well as mutator technology. In addition, he initiated and led collaborations with Seattle Genetics that focused on antibody-enzyme fusion proteins. Prior to his work on biotherapeutics, Dr. Schellenberger directed projects optimizing enzymes for industrial applications as well as microbes for metabolic pathway engineering.

Dr. Schellenberger received his Ph.D. from Leipzig University, where he studied protease catalyzed peptide synthesis. After postdoctoral studies at the Institute for Protein Research in Pushchino (Russia), he moved to the University of Göttingen where he developed a novel method for the production of peptides from recombinant peptide-multimers. After a postdoctoral fellowship with Bill Rutter at the University of California, San Francisco, Dr. Schellenberger joined Genencor in 1994. Dr. Schellenberger is the author of over 40 scientific papers and an inventor on more than 70 issued and pending patent applications. He is also the recipient of the Karl Lohman award of the German Society of Biochemists.
