Roger Bryant studies how the chemical signals preserved in ancient rocks and fossils (such as carbon, sulfur, and boron isotopes in carbonates and pyrite) can be distorted by processes that happen after burial, known as diagenesis. This work helps refine what these geochemical records actually tell us about past ocean chemistry, oxygen levels, and major events in Earth's history, from the rise of animal life to mass extinctions and warming episodes.

Publication output has grown over the last decade, rising from about one paper per year in 2017-2019 to a more active and somewhat variable pace of several papers per year since 2020-2021.
