Principal Research Scientist

Role at ANSTO

Debashish leads the Aquatic Ecosystems and Food Provenance projects at ANSTO, where he uses isotopic and nuclear techniques to advance fisheries, aquaculture and wetlands research into the 21st century, providing contemporary solutions to a number of issues facing Australian industries and environments. His research offers insight into the structure, function and health of aquatic ecosystems, which may be used to improve the sustainability of our environment. Debashish is also at the forefront of food fraud research, using nuclear techniques to provide traceability and quality authentication to protect Australian industries and consumers


Stable isotopes ecology; trophic linkages; food web connectivity; trophic pathways of energy and nutrient in aquatic ecosystems; mixing model; anthropogenic pollutant in aquatic ecosystems; blue carbon sequestrations by wetlands and fish; tracing carbon connectivity between groundwater and surface water food webs; isotope and elemental fingerprinting of biota; methods for food provenance and quality authentication; cost-effective and environmentally friendly aquaculture
