Dr. George C. Ho is a Senior Professional Staff at The Johns Hopkins University Applied Physics Laboratory (JHU/APL).  He received his B.S. (Summa Cum Laude) in physics at Augsburg College in 1991. From 1991 to 1998, he was at the University of Maryland Space Physics Group where he obtained his M.S. (1996) and Ph.D. (1998) both in physics. His current research interests include energetic and suprathermal particle instrumentation, planetary magnetospheric ions, isotopic and elemental composition in both solar energetic particle and shock associated energetic storm particle events. He is currently the Lead-Investigator on the ESA’s Solar Orbiter EPD/Suprathermal Ion Spectrograph instrument; Instrument Scientist on the MESSENGER Energetic Particle and Plasma Spectrometer (EPPS); Instrument Scientist on the Magnetospheric Multi-Scale Mission Energetic Particle Detector (EPD) investigation; Co-Investigator and Instrument Scientist on the ESA's Juice PEP/JoEE instrument; Co-Investigator on the ESA’s Bepi-Colombo SERENA/Strofio instrument; Co-Investigator on the Solar Probe Plus Solar Wind Electrons Alphas and Protons (SWEAP) investigation.
