Professor Kliti Grice

Kliti Grice

John Curtin Distinguished Professor Kliti Grice is an internationally renowned organic geochemist who creatively combines geological information with data on molecular fossils and their stable carbon, hydrogen, sulfur and nitrogen isotopic compositions to reconstruct details of microbial, fungal and floral inhabitants of ancient aquatic environments. She is well known for identifying a geological and environmental basis for the largest mass extinction in Earth’s history, which happened at the end of the Permian Period, ca. 252 million years ago (Grice et al., 2005 Science).

She has extended this research to the Devonian and the Triassic/Jurassic extinction events and established the role of microbes in preserving exceptional well preserved fossils. She has also integrated molecular and isotopic information on plant and algal physiology, microbial ecology, food-webs, organic chemistry, and petroleum geochemistry with the geological record of our planet’s history. Grice has shown how major biological extinction events past can be traced to factors intrinsic to the Earth system, as opposed to external factors such as asteroid impacts.

Her analyses of the natural variation in stable isotopes of lipids present in controlled growth experiments from extant plants, algae and grazing organisms have provided new insights into how these systems function across palaeoecological to modern timescales and across a wide spatial range. Grice’s outstanding research reputation has also attracted many national and international PhD and postdoctoral scholars to the wonders of Earth science.
