Position: Professor of physical and chemical Mineralogy
Area of expertise: physical properties of silicate melts
Research Interests
Experimental melt physics. I study the physical and thermodynamic properties of silicate melts as a function of their composition. This involves, viscosity measurements as well as heat capacity measurements, determination of crystal growth rates, and bubble growth rates as a function of time and deformation-rate in melts. Such investigations are supported by determination of melt structure using NMR and Raman spectroscopic techniques. The information gained from these studies can be used to further our understanding of processes occurring in volcanoes, and the different types of volcanic eruptions and lava flows.
