Karl Kuchler


Ph.D., Technical University of Graz, 1986

Current position

Professor of Molecular genetics, Medical University of Vienna, Austria

Research focus: Karl Kuchler has a long-standing interest in fungal infection biology, molecular genetics, as well as host immune signaling at their intersections with the molecular mechanisms of antifungal drug resistance. His work discovered a novel TLR7-dependent fungal response pathway in dendritic cells, and the group discovered a molecular mechanism underlying the hyper-inflammatory host response upon fungal infections. Finally, the most work uncovered pivotal roles of fungal HDACs/HATs in controlling antifungal drug resistance, stress response, DNA repair as well as virulence.
