Congratulations to Hannah Clevenson — Dr. Hannah Clevenson — for winning the a 2017 Dimitris N. Chorafas Award for  excellence in graduate research. Well deserved, Hannah!!

About the Foundation and the Prize: “The Dimitris N. Chorafas Foundation awards scientific prizes for outstanding work in selected fields in the engineering sciences, medicine and the natural sciences. It rewards research characterized by its high potential for practical application and by the special significance attached to its aftermath. Every year, partner universities in Europe, North America and Asia evaluate the research work of their graduating doctorate students and propose the best for prizing. Depending on the years of association with the Foundation and the size of the sample from which the best researcher is chosen (which must be statistically valid), some partner universities receive two prizes per year; others have one annual prize. The Foundation prizes the best doctoral student(s) in the Hard Sciences in each partner university. These annual awards are of $5,000 each.”
