imageResearch Interests

I use field, analytical, and experimental methods to study magmas as they accumulate in crustal storage regions, mix and equilibrate with other magmas, and ascend to the surface during volcanic eruptions. I am interested in constraining and utilizing the differences in the rates of magmatic processes in order to better understand subsurface plumbing systems and transport processes.

imageI built and maintain the UH Experimental Petrology Laboratory, capable of studying geologic materials at high temperatures (600–1700°C) and a range of crustal pressures (1 bar to 4 kbar).
