I conduct multi-disciplinary research that integrates sedimentology, stratigraphy, geochemistry, and paleontology to investigate the co-evolution of environment and life in Earth history.  All my projects are hypothesis-driven, and typically start with detailed field investigations. Fundamental in all my projects is the emphasis of first-hand field-based results and a hypothesis-driven approach. The multidisciplinary nature of my research requires a holistic understanding of the Earth-life system at both micro- and macro-scales in deep time.
