Juerg Matter

matter_cJuerg Matter is an Associate Professor in Geoengineering at the University of Southampton and an Adjunct Senior Researcher at the Lamont-Doherty Earth Observatory at Columbia University. His research is focused on the intersection between geology, climate change and energy. More specifically, Dr. Matter’s work foscuses on carbon dioxide capture and storage via in situ mineral carbonation in basalt and peridotite, monitoring and accounting techniques for carbon management, climate change mitigation, solute and reactive transport in saturated medi, and tracer hydrology.

Stephanie Pfirman

pfirman_cStephanie Pfirman is the co-chair of the Environmental Science department and a Professor of Environmental and Applied Scientists at Barnard College. She also serves as an Adjunct Senior Research Scientist at the Lamont-Doherty Earth Observatory at Columbia University. Dr. Pfirman research centers on the Arctic environment and the nature and dynamics of Arctic sea ice under changing climate. More specifically, her research seeks to determine the role of sea ice, a transport mechanism unique to the Arctic, in the redistribution of sediments and pollutants in the Arctic.
