My name is Marisa Repasch. I am a PhD student in Geomorphology and Organic Geochemistry at the University of Potsdam in Germany. I am working to understand the role of rivers in the carbon cycle.
I am currently working at the German Centre for Geoscience Research (GFZ-Potsam) with Dirk Sachse (organic geochemistry), Niels Hovius (geomorphology), and Hella Wittmann (earth surface geochemistry). My research is supported by the StRATEGy international research training group funded by the DFG (Link to StRATEGy Program). Our goal is to understand the geomorphic drivers of terrestrial organic carbon transport and preservation through fluvial systems draining the central Argentinian Andes.
In 2016 I earned my M.Sc. degree in Earth and Planetary Sciences at the University of New Mexico, under the supervision of Dr. Karl Karlstrom. There I studied the geologic and geomorphic evolution of the Rio Grande river system using U-Pb detrital zircon provenance and 40Ar/39Ar geochronology. Rivers set the pace of regional landscape evolution, so by learning the rates of change in the Rio Grande and the processes that drive these changes, we now understand why the New Mexico landscape has evolved the way it has.
In 2014 I received my B.S. in Earth and Environmental Science from Lehigh University, where I fell in love with Geology and academia. In addition to discovering my passion, I played on Lehigh’s Division 1 women’s basketball team.
