Research Statement

My primary research focuses on the chemistry of Earth and planetary interiors with a particular emphasis on the role of magma and magma generation process on the differentiation and chemical evolution of terrestrial planets. I use experimental devices such as piston cylinder and one atmosphere furncaces for simulating high pressure-temperature conditions relevant for planetary interiors and various analytical techniques (EMPA, SEM, LA-ICP-MS, FTIR, TIMS) to characterize synthesized and natural samples. Because one limiting aspect of solid-media apparatus is that all experiments are performed in closed-systems, I also use innovative experimental strategies to investigate new topics: simulation of magma circulation, magma-rock interaction or melt segregation, and I use thermodynamic modelling to extrapolate my  data  and/or as support for semi-empirical models.
