Ph.D. Student

Feifei ZhangI joined the Anbar lab in 2014. My work develops and applies geochemical proxies to explore the evolving ocean and atmosphere and their cause-and-effect relationships with the origin and evolution of animals. The redox processes and microorganisms leave dramatic geochemical fingerprints in sediments, I am interested in unraveling the mysteries of these fingerprints with an ultimate goal of better our understanding of co-evolution of environments and animals in Earth history.

The ongoing projects include: (1) geochemical evidence (e.g., U isotope and trace metals) for the causes and consequences of the Permo-Triassic extinction event and the delayed recovery as recorded globally; (2) U isotope variations across major transitional intervals (e.g., the Precambrian-Cambrian boundary, the Mesoproterozoic-Neoproterozoic transition, and the Devonian–Carboniferous transition) and the major carbon cycle perturbation events in deep time (e.g., the Shuram Excursion and the Lomagundi Excursion); (3) mass independent fractionation of oxygen isotopes in CAIs and their W-L rims and the evolution of the early solar system.
