Role at ANSTO


Debashish is a Senior Research Scientist in the Institute for Environmental Research. He is responsible for undertaking research on energy and nutrient pathways and food web interactions in aquatic ecosystems. His work involves applying isotopic and nuclear techniques to better understand the impacts of human activity, water management, land use and climate variability on the structure, function and health of aquatic ecosystems.


Dr Mazumder is currently collaborating with universities and government agencies in Australia and Asia-Pacific countries in various projects that aim to quantify environmental problems to improve outcomes in sustainable management of water resources. 




  • Energy and nutrient pathways and food web interactions in aquatic ecosystems
  • Source and fate of anthropogenic nitrogen in aquatic ecosystems
  • Carbon and nitrogen dynamics and carbon sequestrations in wetlands
  • Human impact on aquatic ecosystem health
  • Tracing carbon connectivity between groundwater and surface water food webs
  • Maximising the benefit of aquaculture operations through the application of nuclear and isotopic techniques
