Personal and Research Interests:

My general research interests are focused on the origin and evolution of magmas and melt in the Earth’s crust and upper mantle. My research combines observations and sample collection in the field (where possible) with laboratory work utilizing experimental petrology techniques. This includes the use of the HSU Experimental Petrology Lab which contains a 1-atm gas mixing furnace and 1.52 cm piston-cylinder apparatus. An updated ExPet lab page will be coming soon.

Courses Taught:

I am the "hard rock" geologist at HSU and teach courses in mineralogy, petrology, instrumental methods, Earth resources, introductory geology, and field geology.
