Jürgen Bajorath is Professor and Chair of Life Science Informatics at the University of Bonn and an Affiliate Professor in the Department of Biological Structure at the University of Washington, Seattle. For the past decade, his research has mostly focused on the development of computational/cheminformatics methods for medicinal chemistry. Among others, current research topics include large-scale analysis and visualization of structure-activity relationships, exploration and prediction of multi-target activities of small molecules, artificial intelligence in chemistry and the life sciences, big data concepts, and data-driven design of novel active compounds.
