I’ve published in computational solid state. My doctorate is, on paper, in earth sciences (mineral sciences!) and you’re going to find all of the materials science department and a few engineers in the vicinity too. Solid-state is one of those five-way borders in the Benelux countries where everyone speaks three languages.

My MSE dept was also colocated with mining engineering. Evolved from the metallurgy dept of a past era. We seemed to have a foot in manufacturing, computational materials, theory and chem lab.
