Dr. Wolf B. Frommer is a Professor in the Biology Department, Düsseldorf University (2017 - present). He earned his Ph.D. in Biology with Peter Starlinger at the University of Cologne in 1987 and undertook postdoctoral research at the Institute for Gene biological Research in Berlin in the lab of Lothar Willmitzer. His lab pioneered the development of metabolite sensors (e.g. sugars, amino acids), hormones (ABA, gibberellin) and reporters of transporter activity (ammonium, nitrate and peptide transporters). A recent development is the Matryoshka concept that enables ratiometric measurements of single-fluorophore sensors. His lab also identified the key sugar transporters from plants and is developing plants that are resistant to pathogens. Recent recognitions include the Laurence Bogorad Award for Excellence in Plant Biology, 2012, a fellowship of the German National Academy of Sciences Leopoldina, 2015, and the Alexander von Humboldt Professorship – International Prize for Research in Germany, 2016.
