My research focuses on metamorphic petrology and geochemistry, particularly of subduction zone rocks. Some of the overarching questions I pursue include:

  • How does subduction zone metamorphism influence arc magmatism?
  • How do the physical processes occurring at the slab-mantle interface impact the mantle wedge and overlying arc structure?
  • What are the spatial and temporal scales of equilibrium in metamorphic rocks?

I approach these questions using petrography, major element geochemistry, trace element geochemistry, isotope geochemistry, geochronology, field observations, and experimental petrology.  In addition to petrologic questions, I am interested in applying microanalytical techniques to any suitable problem, within or outside the Earth and Climate Sciences. A list of current and past projects is available on our geodynamics research group page.

I am the head of the MAGIC Laboratory (MicroAnalytical Geochemistry and Isotope Characterization), which consists of a NWR193UC Excimer laser ablation system coupled to an Agilent 8900 ICP-MS/MS. Much of our current work focuses on method development related to MS/MS technology, geochronology, and trace element mapping.

I also oversee the Experimental Petrology Laboratory, which houses a Bristol-style end-loaded piston cylinder press.

As of 2019, I am the Graduate Coordinator for the School of Earth and Climate Sciences. Please visit our Graduate Studies page for more information about our graduate programs.
