Jacob Waldbauer is a Neubauer Family assistant professor in the Department of the Geophysical Sciences at the University of Chicago. His research combines field observations and laboratory experiments to explore the metabolic basis of biogeochemical fluxes, how microbial community response to environmental perturbations shapes biogeochemical feedbacks, and the molecular fossil record of past life and environments. His laboratory develops novel molecular analytical techniques, particularly using high-resolution mass spectrometry, to address outstanding questions in biogeoscience. He received a B.A. in Physics and Astronomy from Dartmouth College and a Ph.D. in Chemical Oceanography from the MIT/WHOI Joint Program, and was a Stanback/Beckman Postdoctoral Fellow at Caltech. He is the recipient of an Alfred P. Sloan Foundation Research Fellowship in Ocean Sciences and of the Cozzarelli Prize from the National Academy of Sciences.
