About The Position

The Earth Sciences department at Colby College invites applications for a two-year Postdoctoral Scientist position in biogeochemistry. This residential appointment supports Colby’s commitment to high-impact undergraduate education and faculty-student collaborative research. The Postdoctoral Scientist will conduct externally funded research while contributing to undergraduate teaching and mentorship, with the goal of preparing for a future faculty position at a primarily undergraduate institution. The Postdoctoral Scientist will play a lead role in an NSF-funded, multi-institutional research project examining the uptake of toxic metals from dust sourced from the drying Great Salt Lake by native plants and agricultural crops. This work will be conducted in collaboration with scientists at the University of Utah and Indiana University and will involve fieldwork in the Great Basin followed by laboratory-based sample processing and analysis at Colby College.
