To learn more about my research please visit The Henkes Lab

My research interests are the isotope geochemistry of light elements (H, C, N, O, and S) and their use as recorders of the climatological, biogeochemical, and ecological evolution on Earth.  Much of my effort is devoted to making careful and novel stable isotope measurements in the laboratory from samples collected along a wide range of temporal and spatial scales.

If you are interested in joining our growing research group, please contact me directly. I am actively seeking talented and motivated undergraduate and graduate students, post-docs, and visitors to populate our new stable isotope laboratory. Stony Brook is host to an active, collegial, and multidisciplinary research environment. Outside the department of Geosciences, I regularly interact with folks in the School of Marine and Atmospheric Sciences, the Department of Anthropology, and the Turkana Basin Institute, as well as at Brookhaven National Laboratory, the American Museum of Natural History, and other regional research universities.
