Research Interests
I am a geologist specializing in Organic Geochemistry. The primary focus of my research is to decipher ancient biotic forms, paleo-ecosystems and petroleum systems. In particular, I am interested in organic molecular fossils (biomarkers) preserved in sediments for unravelling geochemical information on ancient microbes, flora and fauna across the geological time scale and assessment of energy resources.
