Dr Tom Cresswell

Isotope Ecologist

Role at ANSTO

Research scientist within the Aquatic Ecosystems research group who uses radioisotopes to track contaminant (metal, radionuclides, nanoparticles, nutrients) bioaccumulation and regulation by live plants and animals from simulated environments at environmentally-relevant concentrations. He also uses cutting-edge imaging tools (e.g. autoradiography and synchrotron XFM) at the conclusion of exposures to determine the localisation of bioaccumulated contaminants within the organism. Tom leads the development of live aquatic animal radioisotope tracing methods in research and manages research program. He is responsible for contributing to the development and implementation of ANSTO’s Environment research objectives through implementation of research plans, targets and activities to deliver research outcomes.Tom is responsible for the oversight of projects within assigned research program by review and reporting on project plans, coordination and allocation of resources and shared responsibility for budget control and expenditure.
