UNIVERSITY PARK, Pa. — Andrew Shaughnessy, a doctoral student studying geosciences in Penn State’s College of Earth and Mineral Sciences (EMS), was awarded a 2019 Graduate Research Fellowship from the National Science Foundation. He is one of seven EMS students and 24 Penn State students to receive the honor.
