Elizabeth Ceperley is a PhD student in the Department of Geoscience and studying Quaternary paleoclimate and glacial geology. Liz earned a BS in Geology from Beloit College and an MS in Geological Sciences from the University at Buffalo. Her PhD research spans the Arctic and North America, looking at the dynamics of the Laurentide and the Greenland Ice Sheets on varying timescales. She is using 10Be cosmogenic dating to constrain Holocene fluctuations of Petermann Glacier in Northwest Greenland; and Stateside, she is using the geochemistry of sediments to examine the rerouting of the Wisconsin River during the middle Pleistocene (~ 1 million years ago). More about Liz and her current projects can be found at here website.
Cameron Batchelor is a Master's student in the Department of Geoscience studying Quaternary paleoclimate and geochemistry. Cameron earned a B.S. in Geology from Appalachian State University, where she conducted a senior thesis on U-Pb geochronology of Late Devonian rocks from Mongolia. Her Master's research involves studying speleothems from the Cave of Mounds, located in southwestern Wisconsin. She will be conducting high precision U-Th dating to further constrain the glacial history of Wisconsin, including growths and retreats of the Laurentide Ice Sheet during the past ~250 kyr.
Richard Becker is a PhD student in the Department of Geoscience and working to quantify the importance of preexisting bedrock fractures on rates of glacial landscape evolution. Richard earned a BS in Geological Sciences and a BA in History from the University of Maine and a MS in Geology from the University of Wisconsin-Madison. He has studied glacial geology from Patagonia to Alaska and is currently working in the Sierra Nevada Mountains of California. In particular, he is studying the landscape of Yosemite National Park and comparing it with other landscapes in the Sierra Nevada that are lithologically identical, but substantially different in their fracture characteristics. He is co-advised by Basil Tikoff and Shaun Marcott.
Aaron Barth is a postdoctoral researcher in the Department of Geoscience studying the glacial geology of the late Pleistocene and Holocene. Aaron earned his B.S. from George Mason University and his PhD from Oregon State University under the mentorship of Peter Clark. Part of his PhD research used 10Be cosmogenic dating to develop a deglacial chronology of alpine glaciers in Ireland. Additionally he used geostatistical analyses of multiple climate proxies to characterize variability across the Mid-Brunhes Transition (~430 ka). Aaron’s research at the University of Wisconsin-Madison involves using cosmogenic surface exposure dating methods to determine a chronology of mid-latitude glacier fluctuations from North and South America. We hope to address a model-data discrepancy and fill in a high-elevation, mid-latitude gap in the data used in glacier fluctuation syntheses. More about Aaron and his current projects can be found on his website.
Jeremiah Marsicek is a postdoctoral researcher in the Department of Geoscience at UW-Madison. Jeremiah earned his B.S. in Physical Geography from UW-Madison in 2008, and his M.S. (2011) and Ph.D. (2016) in Geology and Geophysics from the University of Wyoming working with Dr. Bryan Shuman. Jeremiah’s Ph.D. work involved developing statistically-robust paleoclimate reconstructions based on >1600 fossil pollen datasets from Europe and North America to understand how gradual and abrupt changes fit into hemispheric patterns of climate change. During Jeremiah’s M.S. work, he evaluated the drought history using lake sediments on Cape Cod to test the effects on vegetation changes using ground-penetrating radar (GPR), grain size and loss-on-ignition (LOI) analyses, radiocarbon dating, and fossil pollen data. Jeremiah’s postdoctoral research at UW-Madison involves developing detailed reconstructions of regional and global moisture and temperature changes across the world over the last 11,000 years, using the data to better inform existing and ongoing climate modeling efforts to provide quantifiable solutions to ongoing data-model disparities. More about Jeremiah and his current projects, research questions, and publications can be found on his website.
Claire Vavrus is a BS student in the Geological Engineering Department. Claire's undergraduate research in the Marcott lab uses cosmogenic surface exposure dating to determine the timing of late Holocene glacier retreat in the Front Range of central Colorado and the Beartooth Mountains in south central Montana.
Alexander Horvath is a BS student in the Material Science and Engineering department. Alex's undergraduate research in the Marcott lab is focused on the dynamics of the Laurentide Ice Sheet using surface exposure dating of glacial erratics. His research will help constrain the geometric history of the Laurentide in upstate New York during the late Pleistocene, which will place further constraints on its contribution to sea level over this time span.
