Bio

Michael E. McHenry has expertise in soft magnetic nano-composites for power and energy applications. He studies field processing of materials, and structural and magnetic properties as a function of fields (magnetic, strain), temperature, and frequency. He directed a Multidisciplinary University Research Initiative (MURI) on high temperature magnetic materials for aircraft power applications. He led an ARPA-E program on magnetic materials for power electronics and worked more than 15 years with Magnetics, Inc., PA before transitioning technologies to NASA Glenn and Fort Wayne Metals, Indiana.

He was a 2013 IEEE Distinguished Lecturer; 2014 TMS Awardee for Research Excellence in Electronic, Magnetic and Photonic Materials Research; and was subject the 2016 TMS Symposium in Honor of M. E. McHenry. He was technical evaluator for the NATO AVT-231 Meeting: Scarcity of Rare Earth Materials for Electrical Power Systems, Brussels, Belgium (Oct. 2014), and continues to advise Rare Earth scarcity. He was a 2016/17 NATO Series Lecturer on Rare Earth Criticality. He served as the General Chair, Editor, Publication Chair, and on Program Committees for the Magnetism and Magnetic Materials and Intermag Conferences. He has more than 350 publications with over 11,000 citations. McHenry co-authored the text “Structure of Materials,” Cambridge University Press, 2007 and 2012, and has 5 patents in the field.

Education

Ph.D. Massachusetts Institute of Technology

Research

McHenry's research focuses on developing new magnetic materials, processes and unique designs for power converters and motors. His work looks to substantially reduce the size of industrial grid transformers and converters and motors for electric vehicles and other applications. He works on magnetocaloric cooling and sensing applications of magnetic materials as well. He serves on a NATO panel investigating materials criticality issues.
