Laboratory of Paleoenvironmental Research

The Department of Geography’s Laboratory of Paleoenvironmental Research in the Science and Engineering Research Facility is dedicated to the study of soils and sediments as archives of climate and environmental history.  Directed by Drs. Sally Horn and Yingkui (Philip) Li, the lab includes facilities and equipment for recovering and analyzing sediment cores from lakes and wetlands, sampling and analyzing soil profiles for paleoenvironmental research, and for preparing rock samples for cosmogenic nuclide analysis.  Research projects in the Laboratory of Paleoenvironmental Research are supported by grants from NSF to faculty and students, grants and contracts from other federal agencies and private foundations, and by UT’s Office of Research.  The photos below show some of the facilities and past and present students in the lab.
