Nick Bader

Associate Professor of Geology (Sabbatical 2023-2024)

My research interests include Quaternary and modern ecology, the global carbon cycle, soil biogeochemistry, Quaternary climate change, and catchment hydrology. My interest in geology was sparked as a child after seeing the remains of prehistoric creatures at the Museum of Natural History in New York. After high school, I went on to study geology at Earlham College in Richmond, Indiana. During college, a summer job excavating an archeological site along the Ohio River got me interested in palynology and plant macrofossils. I pursued this interest for my Master's research at the University of Arizona at Tucson, where I used fossil pollen from Death Valley's Badwater Basin to reconstruct Quaternary climate changes. After graduating from the University of Arizona, I extended my study of ecology and climate change to modern ecological settings. At the University of California at Santa Cruz, I earned my doctorate for my work on the influence of plants and soil microbes on the global carbon cycle, and on global climate. I am lucky to be a part of the geology department at Whitman College, where I have been teaching geology, geographic information systems, soils, and environmental studies since 2007. My current research interest is paleosols (ancient buried soil horizons) and what they can tell us about past climate.

GEOL 125 - Environmental Geology

An introductory geology course focused on human interaction with the environment and earth resources.

GEOL 229 - Geology and Ecology of Soils

A course focused on the dynamic systems of soils and soil formation, and the role soils perform in ecosystems.

GEOL 258/358 - Regional Geology

A 4-day field course for students to sythesize geologic concept and learn field skills.

GEOL 301 - Hydrology

A course focused on understanding water resources, including surface and groundwater and their role in the larger water cycle.

GEOL 418 - Introduction to Geographic Information Systems

An exploration of the applications and the conceptual framework for computer GIS, with labs teaching the use of ArcGIS Pro.
