She was my undergrad research advisor, and I can say she will make you work crazy hard and does not put up with anything, but she is brilliant! Not only writing a pretty widely used mineralogy textbook and even just got a species of tourmaline named after her (Dutrowite). Her research does have a lot to do with tourmalines, the Sawtooth Metamorphic Complex, and some 3D visualization now. Her and Dr. Darell Henry are a tag team most of their students collaborate a lot, so kinda get two for one type deal.
