Using Isotopes to Track the Origin and Evolution of Life

Measurement of stable isotope ratios at high precision is enhancing our understanding of an extraordinary range of processes in the origin and evolution of the solar system.

Isotope measurements are essential in determining climate temperature variation and making sense of paleo climate records. Dr. Thiemens will describe the discovery of new physical-chemical processes that are deepening our understanding of the atmosphere. Used for applications including studying the oldest rock record on Earth through time, high precision measurements of stable isotopes of sulfur are opening new windows to the past. Dr. Thiemens will share advances in isotope detection and his vision for what more can be learned using these techniques.
