Main fields of research and expertise

The central theme of the research of Emma Rochelle-Newall is the study of the ecology of heterotrophic bacteria in aquatic environments. She also looks at how anthropogenic impacts such as increasing inorganic and organic waste alter the transfer of carbon between the autotrophic and heterotrophic compartments in order to understand the impacts of human activities in aquatic systems. She has experience of working with a wide range of techniques (cultures, mesocosms, in situ) and in a wide range of situations (ship, field, laboratory) and countries (Vietnam, Laos, New Caledonia, Fiji, USA, and across Europe). Another, more recent aspect of her work concerns how pathogens disseminate and proliferate in aquatic ecosystems and how environmental degradation in developing countries is altering the ecology of these microbes. She also regularly gives courses on how to write scientific articles for scholarly journals. These classes are specifically aimed at building the research capacity of students and young researchers from developing countries.
