This research programme investigates processes involving volatiles and their interactions with crystals and melts in magmatic systems. I, together with students and colleagues, will investigate volatile exsolution from melts to form bubbles, develop new ways to estimate volatiles in ancient magmas and degassed into the atmosphere, explore the role of minor volatiles in volcanic eruptions, quantify the ability of volatiles to transport Cl, S and ore metals at magmatic conditions and explore their influence on the delayed nucleation of crystals in magmatic systems. This research program is centred around experimental measurements and computer simulations, and involves collaboration with colleagues working in the field.

该研究计划研究涉及岩浆系统中挥发物及其与晶体和熔体相互作用的过程。我将与学生和同事一起研究挥发物从熔体中溶出形成气泡，开发新方法来估计古代岩浆中的挥发物并脱气到大气中，探索次要挥发物在火山喷发中的作用，量化挥发物在岩浆条件下输送氯、硫和矿石金属的能力，并探索它们对岩浆系统中晶体延迟成核的影响。该研究计划以实验测量和计算机模拟为中心，并涉及与该领域同事的合作。
