I’m interested in further developing applications of stable isotope ratio analysis for sourcing humans, specifically focusing on hydrogen of bone collagen. While there has been extensive research on the utility of carbon, nitrogen, and sulfur in collagen to investigate diet and movement, much less had been done with hydrogen. However, recent research has suggested hydrogen isotope ratios in collagen may be related to both food and water.
