Professor Fike is interested in the detailed working of global biogeochemical cycles, their evolution over Earth history, and their impact on biological evolution.
Professor Fike leads the Stable Isotope Biogeochemistry Group, who focus on using geochemical analyses (predominantly those of the stable isotopes of carbon, nitrogen, oxygen, and sulfur) to understand biogeochemical cycling in the modern and the ancient. They make use of both gas-source isotope ratio mass spectrometers (IRMS) and secondary ion mass spectrometry (SIMS), including our new Cameca ims 7f/geo instrument installed in Dec 2013.
