Dr. Ying Cui is an assistant professor, Earth and Environmental Studies, at Montclair State University. She received a PhD in Geosciences and Biogeochemistry from Penn State in 2014.  Dr. Cui is a geochemist using Earth system model to investigate changes in climate and the geochemistry of ocean and land.

Specifically, Dr. Cui is interested in time intervals in the geologic past when the rate of greenhouse gas release is faster than the background rate, for example, mass extinction events and extreme global warming events. Her primary tools are stable isotopes of carbon (bulk carbonate, organic matter, and compound specific), oxygen (tree ring and cellulose), and nitrogen (bulk organic matter) and Earth system model of intermediate complexity equipped with the cycles of these elements. Dr. Cui is also interested in uncertainty quantification using a variety of statistical approaches to investigate the changes in temperature in response to a doubling of pCO2 (known as climate sensitivity).
