My research focuses on how biological markers could preserve information on microbial evolution/emergence and environmental shifts over geological time scales. One of my research focus is to use biomarker to better constrain the first appearance of eukaryotes and further compare with fossil records during Mesoproterozoic era. My another interests is to use biomarker and bulk techniques to better understand the evolution of South Atlantic rifts and sag basins during earth Cretaceous era.
