Professor Katherine Freeman recently visited the Sprigg Geobiology Centre at the Environment Institute to talk about her research in a seminar entitled, “A haystack from a needle: using biomarkers to understand ancient forest structure”.

In this interview with Ewart Shaw of Radio Adelaide, she discusses isotope biogeochemistry.

Olduvai is a magic word for palaeontologists, the home of our earliest ancestors.

Traces of their lives are analysed to give us a sense of who they were and how they lived. One of the most intriguing areas of research is in the field of isotope biogeochemistry, and Professor Katherine Freeman, visitor to the Sprigg Geobiology Centre, is one of the world’s leaders in this area.
