Measuring geologic time is of fundamental importance to understanding the history of our Earth and solar system. The age constraints provided by geochronology are critical for determining the rates of many physical, chemical and biologic processes that shape our planet. My research focuses on the acquisition, improvement and application of geochronologic data. The U-Pb system is highly versatile, capable of providing extremely high-precision timing constraints on the formation and cooling history of rocks. My specific research projects are diverse, from linking global extinction events to large igneous province eruptions, to measuring the thermal and erosional history of Earth’s oldest continental crust.
