THE PARAI LAB

We make high-precision measurements of isotopes in rocks to better understand the formation and evolution of planetary bodies.

Check out our new PHOTOS page with images from recent field work, the lab build, and other fun efforts from our group!

Dr. Rita Parai

I am a high-temperature isotope geochemist who primarily uses noble gases to address questions about how planetary bodies form and evolve over time. Explore these pages to learn more about my research group, our laboratory facilities and the research we pursue.

Parai Lab Research

Our Research

We pursue topics related to the early Earth, the nature of mantle heterogeneities, chemical constraints on geodynamics, volatile origins and transport on Earth and other planetary bodies, and planetary atmospheres.
