Research Interests:
I am interested in how naturally-occurring variations in stable isotope ratios can be used as markers for nutritional and physiological processes. Currently a large portion of my research is devoted to the development of these markers for use in nutritional epidemiology. I work closely with the Center for Alaska Native Health Research at UAF [CANHR] to develop tools for linking dietary patterns to chronic disease in Alaska Natives and other populations. If you are interested in working in my lab, please send me an email with your interests.
