I seek to understand whether the Earth and life on it are unique – how did life emerge and survive the changing environmental conditions on this planet? Is it possible that life could have arisen elsewhere in our universe? To address these questions, I study Earth’s 4.6-billion-year history preserved in the rock record. As a paleobiogeochemist, I search for the earliest traces of single-celled life that are preserved as fossilised biomolecules, called biomarkers. It is so cool that we can use biomarkers to reconstruct microbial ecosystems and environments in Earth’s early history! However, there are missing links between some biomarkers and microorganisms, resulting in inaccurate reconstructions of Earth's past ecosystems and environments. I am currently pursuing a PhD investigating some of these missing links.
