Mark is a professor who works on magmatic and metamorphic systems. His work is multi-disciplinary, with an emphasis on unraveling tectonic histories by understanding preserved minerals and their geochemical signatures. He employs and develops methods for studying chemical equilibrium and disequilibrium in rocks – these aim to illustrate both the paths that rocks and melts take through the crust and the duration over which they evolve. Mark is currently working in diverse settings, from subduction zones to ultra-high temperature terranes.
A new aspect of Mark's work concerns the interaction of atmospheric dusts with aircraft engines. Mark's interest here involves everything from cold particle breakage during high-speed collisions with engine parts (and resultant engine damage) to the reaction and melting of those particles – metamorphism at a very different scale!
Mark arrived at Virginia Tech in 2012. Before this, he was a research associate at ETH, Zürich, a Ph.D. student at the University of Cambridge, and an undergraduate at the University of Bristol.
Mark's research is primarily in Metamorphic Petrology, and he runs the Metamorphic laboratory.
