Application of marine microfossils (planktonic foraminifera) to studies in biostratigraphy, paleoceanography, and biotic evolution. My research interests span a broad spectrum of spatiotemporal scales ranging from global patterns of deep-sea sedimentation over the past 150 million years down to micrometer-sized geochemical measurements within an individual microfossil. The overarching goal is to develop a clearer picture of how ocean-climate change relates to evolution of marine ecosystems, with particular emphasis on past global warming events and carbon cycle perturbations that have occurred over the course of Earth history.
