  • Evolution of Antibiotic Resistance

How will microbial communities evolve in response to environmental change, antibiotics or phage therapy? Mike and his lab are focused on determining the network of genes required for antibiotic and multidrug resistance. To study this question, the team propagates populations of bacteria (and other microbes) for 1000′s of generations in a variety of laboratory environments. Microbes grow and divide very quickly, providing a means for directly observing evolution as it happens. The goal is to understand how antibiotic resistance evolves, so that evolution can be taken into account for the development of novel strategies to prolong the use of current antibiotics and to identify novel drug targets.

Dr McDonald leads the Microbial Experimental Evolution laboratory in the School of Biological Sciences at Monash University. He completed his PhD in Evolutionary Genetics at the Institute for Advanced Study at Massey University in New Zealand in 2009. After that, he took up a Distinguished Postdoctoral fellowship at the Institute of Molecular Biology at Academia Sinica in Taiwan. In 2012, Mike moved to the USA to take up a Postdoctoral fellowship in the FAS Center for Systems Biology at Harvard University. He established his research group in 2016. Mike was awarded an ARC Future Fellowship in 2017. Mike is currently a member of the Monash Centre for Geometric Biology.
