    After receiving his Ph.D. for a dissertation detailing an experimental search for antineutrino oscillations, 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 the forward tracking 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 and has been involved in the research and development of semiconductor detectors and VLSI electronics for space-based applications, including silicon and CdZnTe microstrip detectors and ASIC front-end readout electronics. He adapted his semiconductor characterization algorithms and software to characterize of the silicon detectors currently flying on the ACE and Stereo missions. He is currently developing the silicon strip detectors for the proposed Heavy Nuclei eXplorer (HNX) mission and is co-deputy PI. As a member of the High-Energy Cosmic Ray Group, Dr. Krizmanic has been involved in a number of balloon-borne astroparticle physics experiments. His research included the measurement of the atmospheric muon flux as a function of atmospheric depth and the relation to atmospheric neutrino production. He developed the physics and detector Monte Carlo simulations for the Orbiting Wide-angle Light collectors (OWL) experiment, investigating both UHECR and neutrino sensitivities. He is currently leading the simulation group for the Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) Astrophysics Probe study and is deputy PI. He is the PI on a NASA APRA proposal to develop end-to-end neutrino simulations for space-based measurements called nuSpaceSim. He also simulated the response to background radiation of the NICER and PRAXyS X-ray instruments. Dr. Krizmanic is a co-investigator on the ISS-based CALET mission and is co-chair of the US Modeling and Simulation group. Dr. Krizmanic is also involved in developing Phase Fresnel Lenses (PFLs) for X-ray/gamma-ray imaging applications, formation-flying spacecraft development to employ these optics, was the PI on several NASA-APRA funded proposals to develop PFLs, and is the PI on the Virtual Telescope for X-ray Observations (VTXO) NASA Astrophysics SmallSat AS3 study and is the VTXO PI.
