GREENING LAB | ABOUT US
Established in 2016, the Greening Lab is based in the Department of Microbiology at the Monash Biomedicine Discovery Institute, Melbourne, Australia. We are a diverse team of microbiologists, biochemists, ecologists, and bioinformaticians working together to understand the causes and consequences of bacterial persistence within a ‘one health’ framework.
Group Leader: Associate Professor Chris Greening
Chris continues to be amazed on a daily basis by the ‘superpowers’ of bacteria. Following a first-class degree in Molecular and Cellular Biochemistry at the University of Oxford, he undertook a doctorate down under investigating the physiological roles of the hydrogenases in mycobacteria. He then gained postdoctoral and lecturing experience at the University of Otago, CSIRO, and Australian National University.
In 2016, he was appointed as a group leader in Monash University’s School of Biological Sciences and completed an environmentally-focused ARC DECRA Fellowship. In 2021, he moved to Monash’s Department of Microbiology to take up a medically-focused NHMRC EL2 Fellowship. Trained in the fields of biochemistry and microbiology, Chris also has experience in genetics, microbial ecology, and molecular evolution, and enjoys working across disciplines. Away from the lab, he enjoys playing piano and saxophone, exploring Melbourne on his new bike, and getting taken for long walks by his two dogs.
