Ryan McBride
Associate Professor

Dr. Ryan D. McBride is an associate professor in the Nuclear Engineering and Radiological Sciences Department at the University of Michigan, Ann Arbor.  His primary research interests are in plasma physics, nuclear fusion, radiation generation, pulsed-power technology, plasma diagnostics, and the dynamics of magnetically driven, cylindrically imploding systems. His research is conducted primarily within the Plasma, Pulsed Power, and Microwave Laboratory, which includes two linear transformer driver (LTD) facilities: MAIZE (~1 MA, ~100 ns) and BLUE (~150 kA, ~100 ns).  He received his Ph.D. from Cornell University in 2009, where he conducted experimental research on wire-array z-pinch implosions using the 1-MA COBRA pulsed-power facility.  In 2008-2016, Dr. McBride was with Sandia National Laboratories in Albuquerque, NM, where he held appointments as both a staff physicist and a department manager.  At Sandia, Dr. McBride conducted research in nuclear fusion, radiation generation, and high-pressure material properties using the 20-MA Z pulsed-power facility.  Most recently, Dr. McBride’s research has been focused on both experimental and theoretical studies of magnetized liner inertial fusion (MagLIF).  MagLIF is presently one of the United States’ three mainline approaches to studying controlled inertial confinement fusion (ICF) in the laboratory.

Nicholas Jordan
Associate Research Scientist

Dr. Jordan received the B.S.E., M.S.E., and Ph.D. (plasma option) degrees in Nuclear Engineering and Radiological Science from the University of Michigan (UM), Ann Arbor, MI, USA, in 2002, 2004, and 2008, respectively. From 2008-2013, he was with Cybernet Systems, Ann Arbor, MI, where he was involved in the development of microwave vehicle stopping technology. He is an Associate Research Scientist in the Nuclear Engineering and Radiological Sciences Department at the University of Michigan, Ann Arbor, and the Lab Manager for the Plasma, Pulsed Power, and Microwave Laboratory.  His current research interests include high-power microwave devices, pulsed power, laser ablation, high energy-density physics, and plasma discharges.

Adjunct Professor

 

Roman Shapovalov
Post-Doctoral Researcher
Dr. Roman Shapovalov earned his Ph.D. from Idaho State University in 2016. There he developed a novel, compact and portable pulser for x-pinch applications. After completion of his PhD, Dr. Shapovalov was with the University of Rochester (2017-2019), where he conducted research on pulsed-power development for plasma experiments. In January 2020, Dr. Shapovalov joined the University of Michigan, Plasma, Pulsed Power & Microwave Lab, where he continues his research in pulsed power with emphasis on high power microwave generation.
He holds two master degrees, first from Kharkiv State University (1997), Ukraine, for his research of photodisintegration of nitrogen in the intermediate energy region, and second from Idaho State University (2012), for the study of two neutron correlations in photofission of actinides. After graduation, Roman worked at Zaporizhia Nuclear Power Plant (1997–2007), Ukraine, where he was responsible for nuclear-fuel-load safety simulations.
In his spare time, Roman is a recreational runner, exploring nearby trails and training for his next marathon.
