I specialize in developing new tracers in Earth system cycles.These tracers bring fresh perspectives to chronically intractable systems such as atmospheric circulation, biosphere productivity, and nutrient cycling in a changing world. By continually challenging our Earth-system models with improved empirical constraints on natural processes, I hope we can improve predictions of how the Earth system will change in the future.

My work often starts out as nothing more than ideas sketched out on paper, but part of what I love about science is going into the lab (and the field) to test them out. I would rather be wrong than not experiment, because sometimes nature surprises you!
