Dr. Shaun Marcott (smarcott@wisc.edu) is an Associate Professor in the Department of Geoscience at University of Wisconsin-Madison whose work is focused in the broad fields of paleoclimatology, glacial geology, geochemistry, and geochronology. His professional interests span a broad range of geological and climatological questions that typically encompass the last 150,000 years. He is an Earth Scientist, which is reflected in his broad research interests and education in geology, oceanography, and mathematics. He and his research group focus their efforts on developing new approaches to long standing problems in geochronology and paleoclimatology, and spend a considerable amount of time split between the WiscCosmo Lab and conducting geologic field work.

Shan Ye is a PhD student in the Department of Geoscience studying paleoclimate. Shan enrolled as a GIS major (2011 – 13) at Penn State University where he worked on a senior project on the cartographic design of complex road network maps. He earned a B.S. in Earth and Environmental Sciences (2015) at University of Michigan where he conducted a senior research project on environmental issues caused by mining and fracking activities in the Michigan Basin. He earned his M.S. in Geosciences (2018) at University of Tulsa with a thesis on the numerical simulation on final geometries of buckling folds embedded in heterogeneous matrices. Shan’s PhD research at Wisconsin involves meta-data compilation and analysis on paleoclimate reconstruction of different periods in geological history (Holocene and Cretaceous). He is also developing cyberinfrastructure that facilitates data management and sharing between geochronology labs. More about Shan Ye can be found on his website: https://yeshancqcq.github.io/

Andrew Jones is a PhD student in the Department of Geoscience studying paleoclimate. Andrew received a B.S. in Geoscience from Boston College in 2015, where he completed a senior thesis under the advisory of Jeremy Shakun. His thesis tested the freshwater routing hypothesis for abrupt climate change by applying isotope geochemistry to foraminifera to construct a paleodischarge record for the Hudson River. Presently, Andrew works in the WiscCosmo Lab on extracting Be-10 from quartz in order to study current alpine glacier extents across the spine of the American Cordilleras in comparison to their variations throughout the Holocene (the last 11,700 years).

Jeremy Brooks is a PhD student in the Department of Geoscience studying glacial processes. Jeremy received a B.A. in Earth and Planetary Science from Northwestern University in 2020, where he completed a senior thesis reconstructing the Little Ice Age paleo-extent of alpine glaciers in South Greenland and inferring climatic change based on paleo-glacier equilibrium lines. Jeremy’s research at Wisconsin involves studying the physical processes of glacial erosion, using cosmogenic nuclides to infer deglacial chronology and erosion rates in Wisconsin, and studying chemical weathering under glaciers in laboratory-controlled and field settings.
