Present PositionStaff ScientistUniversities Space Research Association NASA/GSFC Code 661 Greenbelt, Maryland 20771 Brief BioAfter receiving his PhD, Dr. Krizmanic was a post-doctorial associate and an associate research scientist at Johns Hopkins, working on the L3 experiment at CERN and performing research and development of novel semiconductor detectors for the SDC experiment that was to be located at the Superconducting Super Collider. Dr. Krizmanic came to the NASA GSFC in 1994 as a NRC associate to develop novel semiconductor detectors, related technologies, and VLSI electronics for space-based applications.1980—1983 Research Assistant Department of Physics and Astronomy Northwestern University 1983 – 1986 Teaching Assistant Department of Physics and Astronomy The Johns Hopkins University 1986 – 1989 Research Assistant Department of Physics and Astronomy The Johns Hopkins University 1989 – 1990 Postdoctoral Fellow Department of Physics and Astronomy The Johns Hopkins University 1990 – 1994 Associate Research Scientist Department of Physics and Astronomy The Johns Hopkins University 1994 – 1995 Associate NRC Research Scientist National Academy of Sciences/National Research Council NASA/GSFC Code 661 1995 – 1997 Senior NRC Research Scientist National Academy of Sciences/National Research Council NASA/GSFC Code 661 1997 – 1999 Research Scientist Universities Space Research Association NASA/GSFC Code 661 1999 – present Associate Research /Staff Scientist Universities Space Research Association NASA/GSFC Code 661 Educational Background1989 PhD The Johns Hopkins University PhD Thesis: A Search for the Oscillation of Muon Antineutrinos to Electron Antineutrinos using the AGS Wide Band Beam 1986 MA Physics, The Johns Hopkins University 1983 BA Physics and Mathematics, Northwestern University Research InterestsDr. Krizmanic has been involved in the research and development of novel semiconductor detectors, related technologies, and VLSI electronics for space-based applications including CdZnTe microstrip detectors, the prototype ASIC front-end readout electronics for the GLAST calorimeter, and silicon tracking detectors and related ASIC electronics. As a member of the High-Energy Cosmic Ray Group in GSFC’s Astroparticle Physics Laboratory, Dr. Krizmanic has been involved in a number of balloon-borne astroparticle physics experiments including ISOMAX and IMAX. His research included measurement of the atmospheric muon flux as a function of atmospheric depth and the relation to atmospheric neutrino production. He is involved in Orbiting Wide-angle Light collectors (OWL) collaboration, having developed the physics and detector Monte Carlo simulations for this future UHECR experiment. His current UHECR research topics include neutrino astrophysics and investigating the effects of clouds on space-based airshower observation. Dr. Krizmanic is also involved in developing Phase Fresnel Lenses (PFL’s) for x-ray and gamma-ray imaging applications, developing and simulating the performance of transition radiation detectors, and a co-investigator to develop a balloon-borne, gamma-ray polarimeter.Research Areas: Astroparticle Physics, particle physics instrumentation with an emphasis on semiconductor detectors and related ASIC electronics, x-ray and gamma-ray optics and instrumentation,, simulation physics, neutrino physics and astrophysics.
