Congratulations Dr. Drombosky
April, 2014
Tyler Drombosky successfully defended his thesis on April 4th, 2014. In his doctoral dissertation, Tyler developed a novel technique for modeling microstructure in deforming, partially molten rocks at the base of the Earth's tectonic plates. Tyler will move on to work at Luminal.

Crystallization of a magma ocean

Earth's first few hundred million years, dubbed the Hadean Eon, remains one of the relatively poorly understood parts of the planet's history. Ancient zircons, likely deposited within a few hundred million years of the giant impact event in calm, surface lakes, indicate that this period was marked by rapid crystallization and cooling from a magma ocean. We are currently investigating a few different aspects of heat loss in a crystallizing magma ocean. These issues include the interaction between crystal settling and heat transfer, thermal interaction between neighboring crystals, and crystal growth.

Graduate student Tyler Drombosky is developing a theoretical toolbox using the Dual Reciprocity Boundary Elements Method (DRBEM), which provides a robust mechanism of modeling multidomain, transient heat transfer problems.
