Ph.D. Student


I started as a Ph.D. student in the fall of 2016, but have worked in the Anbar Lab since my freshman year at ASU (Fall 2012). My research focuses on Earth’s oxygenation history: how and when free oxygen first became available and how this evolved through time. To investigate this I have been involved in the development and application of iron (Fe), molybdenum (Mo), thallium (Tl), and uranium (U) isotopes as paleoredox proxies for perturbations in ancient oxygen.

Constraining the spatial and temporal distribution of ancient oxygenation will increase our understanding of Earth’s evolution. With an eye on the future, by comprehending Earth’s environmental response to past change we can better equip ourselves for what lies ahead.
