Research
My research in igneous petrology focuses on the physical and chemical magmatic processes and integrates fieldwork, laboratory analytical techniques, and modeling. Systematic field mapping, sampling, and observations are followed by XRF whole-rock chemical analyses, petrography, along with crystal size distribution (CSD) analyses and/or SEM analyses. Field and analytical data is then used to estimate physical magmatic properties such as temperature, viscosity, crystallinity etc. and model processes such as emplacement, solidification, layering, etc. and also to estimate timescales of these magmatic processes.
