Welcome to the Tfaily Lab at the University of Arizona

Department of Environmental Science

The research in the Tfaily lab revolves around carbon cycling in terrestrial and aquatic ecosystems, the interactions between microbial communities and organic matter, their geochemical environment and the resulting impact on the whole ecosystem. We use a combination of modern analytical molecular techniques (high resolution mass spectrometry, etc.), geochemical (wet chemistry and gas flux) and isotopic techniques (natural abundance, and isotope enrichment) to answer the who, where and how organic matter degradation and formation takes place in different ecosystems. More specifically we are interested in examining the direct relationship between organic matter composition, the activity of the biological community, the geochemical signature of the activity and how that signature may translate between environments thus enhancing our understanding of the current and past processes that drive our planet.
