Role at ANSTO

Dr Karina Meredith was appointed Director of the new Research and Technology Group for Environment effective 15 January 2024. 

Dr Meredith was previously the Leader of the Environment Group at ANSTO and a Principal research scientist with expertise in hydrochemistry, hydrogeology and environmental site investigations. Nuclear research techniques are an important tool for environmental scientists to understand past climates and anticipate the future | ANSTO. She is an isotope hydrogeologist that has been involved in applying a variety of chemical and isotopic tracers in water to investigate water resource sustainability and water quality in a variety of natural and contaminated environments. She is a technical expert in radiocarbon hydrochemistry and age calculations International collaboration identifies potential threat to water quality | ANSTO.

Water science - groundwater resources at ANSTO

Over the past 20 years, she has led and contributed to a variety of research and commercial water projects throughout Australia (including the Sub-Antarctic ) and internationally, including Sri Lanka and Antarctica Partnering in Antarctic research | ANSTO. She is involved in major partnerships and collaborations with domestic and international universities, government departments and the International Atomic Energy Agency.

Recent research projects include understanding the role of groundwater in contributing to kidney disease in the rural areas of Sri Lanka New partnership | ANSTO, providing expertise for state-wide groundwater investigations using isotopes ANSTO contributes to state-wide survey of groundwater resources in NSW | ANSTOto discovering the hydrochemical secrets of Antarctic lakes and how these unique environments are changing SAEF Goes South for First Fieldwork Season - Securing Antarctica’s Environmental Future (
