In my research, I use novel stable isotope tools to understand climate- and geobiology-related processes that shape our world. During my PhD at Harvard University, I generated triple oxygen isotope records of sulfate minerals to track atmospheric pO2 across the last 550 million years. As an ISEN postdoctoral fellow at Northwestern University, I measured calcium and strontium isotopes across Cretaceous Ocean Anoxic Events to understand marine responses in a high-pCO2 world.

At Penn State, I am an Agouron Geobiology Postdoctoral Research Fellow in the Ingalls group. My research focuses on applying stable isotopes to understand carbonate mineral formation in modern Green Lake. Working in a modern setting allows me to test hypotheses about ancient Earth.
