Dr. Ian J. Cohen is a Senior Professional Staff member at The Johns Hopkins University Applied Physics Laboratory (JHU/APL).  He received his B.A. (with distinction) in Astronomy & Physics from Boston University in 2010. From 2010 to 2015, he attended the University of New Hampshire, where he obtained his Ph.D. (2015) in Physics while working in the Magnetosphere-Ionosphere Research Lab within the UNH Space Science Center. His current research interests focus on experimental space physics, specifically magnetospheric and plasma physics including magnetosphere-iononsphere coupling (including ion outflow, auroral dynamics, and ionospheric feedback); energetic particle dynamics; and plasma and energetic particle instrumentation. He currently serves as Project Scientist for the NASA Magnetospheric Multiscale (MMS) mission Energetic Particle Detector (EPD) investigation and Instrument Scientist for the MMS Energetic Ion Spectrometer (EIS) instruments.
