Timothy Walsh

Timothy Walsh is the Professor of Medical Microbiology and Antibiotic Resistance at Cardiff University and one of the leading scientists into antibiotic-resistant bacteria. He led the discovery of the gene MCR-1 which helps bacteria in becoming resistant to an antibiotic called colistin. By continuously researching and monitoring the spread of new multi-resistant superbugs, he has also become one of the most prominent advocates of responsible antibiotic use. In the past years, there has been a growing awareness of the threat of an imminent “post-antibiotic era” in which common infections and surgeries could – once again – become fatally dangerous.
