How have the continents grown through time? What where the ancient atmosphere, oceans, and biosphere like, and how did they evolve? Are there connections between the solid Earth and its surface, including the biosphere? What analogs can we study on Earth, past and present, to inform us in searching for life and planetary habitability elsewhere in the Solar System? These are some of the major scientific questions that isotope geochemistry can contribute to. Some of our research pursuits involve the study of astrobiology, a broad interdisciplinary approach to addressing the origin and evolution of life on Earth and elsewhere. Others fall more into the category of “the solid Earth”, specifically orogenic systems, past and present. Still others focus on relatively young sedimentary systems. And commonly all involve pushing the boundaries of analytical techniques.
We have grouped our research program into four main themes, with links below:
