My goal in research is to understand the interaction between environmental change and biological evolution using fossils and the sedimentary rock record. How does environmental change influence local and global diversity and ecology? And conversely, how does ecological change affect the physical environment? I am focused primarily on finding answers to these questions on two timescales: 1) the timescale of catastrophic extinction events and their immediate aftermaths (up to a few million years); and 2) the timescale of geological periods and eras (tens to hundreds of millions of years). My research combines micro-scale work on the petrography and geochemistry of individual limestone samples and mineral phases with macro-scale work on the stratigraphy and paleontology of carbonate platforms. In addition to field and laboratory study, I also compile literature-based data and use theoretical models to help constrain interpretation of field-based data.
