Research Interests

I am a geochemist studying the physical and chemical behavior of volatiles, including noble gases, on scales ranging from individual grains to entire planets. I have a background in engineering and the geosciences and draw on my interdisciplinary training to perform high quality experimental, analytical, and numerical work. My research includes:

  • Developing new experimental methods for determining solubility and diffusivity of noble gases and nitrogen
  • High spatial-resolution measurement of noble gases in mineral phases
  • High precision measurement of nitrogen isotopes in natural samples
  • Modelling the volatile contents of planetary bodies, including mantle and atmospheric reservoirs
  • Modeling the onset of mantle regassing via volatile recycling in subducting slabs
