Professor of Microbiology, RMIT University

Mark Osborn is a Professor of Microbiology at RMIT University, Melbourne, Australia.

Mark's research seeks to understand the role, function and ecology of microorganisms within natural and man-made terrestrial, freshwater and marine environments. He seeks to understand how human activities impact upon microbial processes and, in turn, how individual microorganisms and/or microbiomes can respond to and mitigate against a range of environmental pollutants including heavy metals, petroleum hydrocarbons, plastics, pesticides, fertilizers and greenhouse gases.

Mark has published over 90 research journal articles, reviews and book chapters (cited just under 10,000 times) and he is the principal editor of a textbook on Molecular Microbial Ecology.

Mark's media communication activities include interviews on plastic pollution (BBC Radio) and COVID-19 (Sky News Australia).

Mark holds B.Sc. Special Honours (Sheffield, U.K.) and Ph.D. (Liverpool, U.K.) degrees in Genetics & Microbiology.
