So... what is MSE?
Materials science is the study of the relationships between processing, properties, structure, and performance. At some point, you will inevitably be shown "the tetrahedron", so let's get that out of the way now:
For those who have been paying attention, you may have noticed "and engineering" attached to the discipline. MSE covers both fundamental understanding and cutting-edge innovation (i.e., science), as well as practical things, like what to build a bridge with, or how to increase the lifespan of engine components (i.e., engineering).
Between undergraduate research, summer internships, coursework, and graduate school, I've had a chance to dabble in a broad range of topics under the MSE umbrella. Eventually, I may even cover all of them...
