Research

My research pertains to the chemical evolution of felsic magmas. This work entails iterations between field study, laboratory analysis, and experimental validation. For the most part, the experimental programs that we conduct are fundamental to silicate science. These include measurements of crystal nucleation and growth from melt or vapor, interactions among ions during their chemical diffusion through melt, morphologies and preferred growth directions of crystals as functions of growth conditions, elemental partitioning between crystals, melt, and vapor, and stability fields of common and rare minerals of petrologic value. Though foundational in their own right, I have applied these studies to the origins and internal evolution of granitic pegmatites, some of which are the most chemically and texturally complex rocks known (on Earth or elsewhere).
