Permian/Triassic (P/Tr) Boundary Global Events—The P/Tr boundary represents the largest mass extinction in Earth history, yet its causes remain uncertain. I am investigating critical questions related to the extent and intensity of Permo-Triassic deep-ocean anoxia, patterns of upwelling of toxic sulfidic waters onto shallow-marine shelves and platforms, and the relationship of such events to global C-isotopic excursions and the delayed recovery of marine biotas during the Early Triassic. I am working on the P/Tr boundary globally, including sections located in China, Vietnam, Japan, India, Iran, Italy, and Canada.
