Image of osmium isotopic analysis via thermal ionization mass spectrometry using an electron multiplier detector.
Broadly, I am interested in studying the behavior and distribution of elements in the Solar System, the chemical evolution of terrestrial planets. I am an analytical chemist by training, and focus my research around instrumentation and analytical method development. I use isotope geochemistry, major and trace element systematics, petrologic modeling, and any other tools that can help provide insight into the formation and differentiation of planetary bodies. Check out my publications below for specific research topics.
I'm also very interested in creating a positive science culture through mental health awareness, diversity and inclusivity, and science outreach. I am always looking for financial resources to share with other students; I have compiled a list under the financial resources page.
