Roger Hart is a coasts and communities associate fellow at the University of Massachusetts Boston and a PhD student in the Hannigan research group in the School for the Environment. He is broadly interested in critical geobiolocal events, specifically mass extinction events. Hart will be investigating the Permian-Triassic extinction and the reconstruction of the late Permian to early Triassic climate conditions of the Neo-Tethys. His specific focus is on biomarker analysis and compound specific isotope analysis of these sediments to reconstruct the productivity of the Neo-Tethys shelf environments and evaluate the rate of recovery across the extinction boundary. Hart has prior research experience working with chemical, molecular, and microfossils at University of Massachusetts Amherst, where he majored in geology.
