Our Research

Our research focuses on the evolution of life, from the first unicellular microbes and plankton that contributed oxygen to Earth's early atmosphere to the origin of humans and our ecological footprint on the environment.

We employ interdisciplinary approaches, such as paleontology, sedimentology and biogeochemistry to resolve questions about the ancient past. We study the structure of fossil plants and animals, undertake taxonomic studies, and utilize the diversity and specialized adaptations of past life to interpret and reconstruct ancient ecosystems.

We also aim to answer questions about how ecosystems responded to global crises and how they recovered after catastrophic mass extinctions. Our research addresses climate change through geological time and its relationship to biodiversity changes.
