Geobiology Faculty

Dr. Fowle's research focus is geomicrobiology, aqueous geochemistry and limnology.

Dr. Marshall’s research focus is solid-state Raman spectroscopy, in particular understanding the Raman spectrum of hematite, mineralogy, and astrobiology.

Dr. Olcott's research combines organic geochemical techniques with paleontological and geological techniques, to characterize the evolution and preservation of the biosphere through time, especially in intervals of Earth's history where the traditional fossil record is sparse.

Dr. Roberts specializes in hydrochemistry and microbial geochemistry, bridging basic and applied science and focusing on the role of microorganisms on mineral chemistry and weathering as it applies to carbon sequestration, petroleum reservoir diagenesis, paleoclimate, and water quality from the nano- to landscape scales.
