Professional Experience

Gunnar F. Kaufmann was born in Germany and studied Human Biology in Marburg and Greifswald where he received his Diploma in 2001. He then joined Professor Kim D. Janda’s group at The Scripps Research Institute and obtained his Ph.D in Macromolecular and Cellular Structure and Chemistry in 2006, working on generation and engineering of antihapten antibodies as well as bacterial quorum sensing as target of immunotherapy. During his postdoctoral studies, he investigated the effect of bacterial quorum sensing molecules on the mammalian host in a joint position between Professor Janda’s group and the laboratory of Professor Richard J. Ulevitch at TSRI.
