Biography in Brief

John Judge’s research interests are in the area of vibration and dynamics of complex structures, including vibration localization in near-periodic structures, resonant micro- and nano-mechanical systems (MEMS/NEMS), nonlinear dynamics, laser vibrometry and experimental characterization of systems using vibration and acoustics, and seismic/acoustic detection of landmines and improvised explosives.  Prior to joining CUA, he held a National Academy of Sciences Research Associateship at the Naval Research Laboratory in Washington, D.C.
