Personal profile


Dr Deepa Varkey is a marine biologist with research interests in microbial ecology, coastal primary productivity and molecular mechanisms of thermal tolerance in marine organisms. Her current research project focuses on understanding and predicting how the structure and function of marine microbial communities vary across space and time in response to environmental change.

By utilising molecular tools and Machine Learning, her research attempts to predict microbial provinces in the oceans using species distribution models based upon extensive microbial community and environmental data collected by the Marine Microbes and Australian Microbiome projects. A key goal of this research is the development of tools to monitor the health of Australia's marine provinces.
