I am a geologist who uses geochemistry, geochronology, and petrology to interrogate the thermal and chemical history of Earth's lithosphere. Much of my work can be classified as "geochemical signal processing": using statistical tools (PCA, ICA, cluster analysis) to break down and interpret large geochemical datasets, including those I collect (often by LA-ICPMS) or from aggregate data (e.g., GEOROC). My approach involves field work in modern and ancient mountain belts, followed by high-precision analytical and modelling work. Some recent efforts include large-scale statistical projects on compiled zircon and whole-rock igneous data. Recently, I have combined these approaches with geophysical data to probe modern continental lithosphere.

I am currently a postdoctoral scholar at Penn State, working closely with Drs. Andy Smye, Maureen Feineman, and Jesse Reimink. Pennsylvania has a rich natural and cultural history, and in my spare time, you can find me investigating local geology, hikes, birds, and mushrooms.
