Karina Meredith


Role at ANSTO


Karina is a research scientist in the Isotopes for Water project. She is working in the fields of hydrochemistry, hydrogeology and isotope hydrology on a variety of projects located throughout Australia. Her research interests lie in applying a variety of stable, radiogenic and cosmogenic isotopic tracers to investigate groundwater resource sustainability and the suitability of aquifer systems as potential low resolution climate archives.
