Facility Director of the Laboratory for Isotopes and Metals in the Environment (LIME) at Penn State University. My research interests include low temperature, non-CHONS stable isotope studies in carbonates and their tracer applications in biogeochemical cycling. I travel a lot with my work, participating in both field excursions and conferences. It is important to have a camera on me at all times, you never know what you may find right around the corner; this world is full of wonders simply waiting to be shared.
