My research is aimed at understanding the physical and biological processes that have regulated biodiversity through time. Our lab studies the exceptionally rich and complete fossil record of marine invertebrates, and integrates field collections, geochemical observations, and statistical analyses to unravel the drivers of macroevolutionary change at a variety of timescales. A particular focus is the complex relationship between major climate perturbations and extinction events. Comparing patterns of differential extinction and survival with multi-proxy records of environmental change through time illuminates the ways in which extinction patterns during these events differed from those preceding and following them, which can fingerprint the processes most responsible for driving biotic turnover.
