Although we have a wide range of research interests, the majority of research in EPIC focuses on the chemistry, conditions, and timescales of magma formation as pertain to planetary differentiation and volcanic hazards.
Check out this article on some of the exciting research topics in Experimental Petrology, many of which we explore in EPIC.
