Personal profile
Research interests
The Fike Lab focuses on using isotopic signatures (primarily those of C, N, O, S) of aqueous, organic, and mineral phases to understand both modern and ancient microbial metabolic activity and global biogeochemical cycling. As such, my interests cover spatial (and temporal) scales ranging from globally averaged biologic productivity to cell-specific microbial metabolic activity. We make particular use of secondary ion mass spectrometry, using a Cameca 7f-GEO instrument in my lab that is capable of mapping elemental and isotopic compositions in microbial cells down to approximately 100 nm.
