Prof. Jochen Brocks
Jochen is a Professor at the Research School of Earth Sciences at the Australian National University.
He received a Masters in physical organic chemistry from the University of Freiburg in Germany and a PhD from the University of Sydney in 2002. He was a Junior Fellow of the Harvard Society of Fellows from 2001 to 2004.
He calls his field of research ‘Paleobiogeochemistry’ as he is fascinated by biological processes in deep time, from the origin of life to mysterious ecosystems in Earth’s earliest oceans, and events that may have spawned the evolution of complex cells and multicellular life.
To find clues about ancient ecosystems, he studies molecular fossils of biological lipids (biomarkers) that can be preserved in sedimentary rocks for billions of years. Currently he and his students investigate the question why large, multicellular and active creatures appeared on Earth some 600 million years ago, and whether ancient oceans harbored a lost world of complex life that left no traces, apart from some obsolete molecules.
