Dan received his Ph.D. and M.S. in Physics from the University of California at San Diego (1997 and 1995), and his BSEE in Electrical Engineering from Arizona State University (1989). His current research topics include multiple-input multiple-output (MIMO) wireless communications, MIMO radar, cognitive radios, radio network performance, geolocation, and statistical signal processing for anticipatory physiological analytics. Before moving to ASU Dan was a senior member of the technical staff at MIT Lincoln Laboratory (1997-2012). Employed by General Dynamics (1989-1993), he designed rocket avionics and performed magnetic field calculations and optimization for high-energy particle-accelerator superconducting magnets. His doctoral work (1993-1997) was in the area of high-energy particle physics.
