Canada Research Chair in Geomicrobiology
The overarching goal of my research is to improve our capacity to predict and respond to global change by creating new knowledge of the earth system. Microorganisms and prokaryotes in particular have been the engines of biogeochemical cycles throughout Earth's history. Eukaryotes rose to prominence with the evolution of land plants some 400 million years ago, and now humans are playing key roles in shaping fluxes of matter and energy at a global scale. Going forward, our survival as a species will be linked to our capacity to predict and manage our own interaction with the earth system. Qualitative and quantitative models that can describe biogeochemical cycles, reproduce past events, and predict future change are tools needed for managing human interaction with the earth. The information, or the 'blueprint', on how to run biogeochemical cycles is coded in the microbial DNA that is dispersed throughout the world's oceans, soils, and the deep biosphere. How this information translates into networked, microbially-catalyzed geochemical reactions remains largely uncertain. The utility and performance, therefore, of current models of biogeochemical cycling are challenged by a lack of explicit definitions of the biological information carriers (eg. DNA, RNA, protein) that ultimately regulate and control biogeochemical cycles and their dynamics through time.
