Gordon works on a variety of projects, involving analysis of radiogenic and mass-dependent isotopes. She has been a pioneer in developing the Mo and U isotope proxies for oxygenation levels in marine sediments in the early Earth. 


Another central research theme is developing and applying geochemical techniques to problems relevant to modern society, and to humans in particular. Current projects funded or in active development include:

  • Isotopic taphonomy: examining the preservation of H, C, N, O, Sr and Pb in human tissues to predict the geographic origin of unknown decedents

  • Human geolocation: validating C, N, O, H, and Sr in human bones and teeth for cultural affiliation and geographic residence history (in collaboration with several human decompositional facilities (University of TennesseeTexas StateColorado Mesa University)

  • Cancer: analysis of Ca isotopes in serum and urine to predict progression of multiple myeloma from changes in bone mineral balance

  • Astronauts: analysis of Ca isotopes in urine of astronauts from the International Space Station to determine the efficacy of exercise and anti-osteoporosis drugs in protecting astronauts from bone loss during space flight

  • Obesity and diabetes: Use of C and N isotopes to record dietary patterns independent of self-report, and their value in monitoring the impact of exercise on metabolism by comparing indirect calorimetry using mobile smartphone technology and analysis of carbon in breath and carbon and nitrogen in hair.


If you’d like to hear more about the forensics research, you can listen to the podcast, “Just Hairy Isotopes”, produced by the Forensic Center of Excellence, and watch a webinar about the taphonomic research at the National Institute of Justice’s grantee’s symposium at the American Academy of Forensic Science conference in February 2017.
