We employ a variety of conventional and sychrotron based methods to analyze samples generated from laboratory and field based studies. In particular, we utilize state of the art spectroscopic and microscopic techniques (e.g. micro and bulk X-ray absorption spectroscopy, micro-fluorescence X-ray tomography, and micro-focused X-ray fluorescence spectroscopy) as well as computational tools (reactive transport modeling) to link molecular and field-scale studies of element cycling.
