Welcome! Among other pursuits, I am a geologist. I study modern and ancient rocks using field, analytical, and modelling work. My expertise is in hard-rock geochemistry, geochronology, and petrology, which I use to probe the history of Earth's lithosphere and surface.

I am an Assistant Research Professor at Penn State, which primarily involves running the "LionChron" LA-ICPMS laboratoryPennsylvania has a rich natural and cultural history, and in my spare time, I investigate local geology, hikes, birds, and mushrooms.
