Welcome! Among other pursuits, I am a geologist. I study modern and ancient mountain belts 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.

I am an Assistant Research Professor at Penn State, which primarily involves running the "LionChron" LA-ICPMS laboratory and includes working closely with Drs. Jesse Reimink, Andy Smye, and Maureen FeinemanPennsylvania has a rich natural and cultural history, and in my spare time, I investigate local geology, hikes, birds, and mushrooms.

New in 2023! Our lab was recently featured on NPR's All Things Considered and Shortwave; please listen to hear about our work!
