Zarija Lukić is a staff scientist leading the Computational Cosmology Center at Berkeley Lab. He earned his astrophysics PhD in 2008 from the University of Illinois at Urbana-Champaign and has been a postdoctoral researcher in the Theoretical Division of Los Alamos National Laboratory (2008-2011) and the Computational Research Division of Lawrence Berkeley Lab (2011-2013).
The main topic of Zarija's research is the formation and evolution of the structure of the Universe, with the current focus on the Lyman-alpha forest observed in quasar spectra. An essential component of his research is developing new computational methods for modeling and interpreting physical systems: building simulation codes that can efficiently run on the largest supercomputers, as well as methods for extracting scientific insights using simulation models and observational data from sky surveys. Over the past 20+ years, he was the P.I. on many projects using world-leading supercomputers, including those at NERSC, the National Center for Supercomputing Applications (NCSA), the Los Alamos Supercomputer Center, the Oak Ridge Leadership Computing Facility (OLCF), and the Argonne Leadership Computing Facility (ALCF). He is currently LBL P.I. on SciDAC-5 project "Enabling Cosmic Discoveries in the Exascale Era", and on ECP project "Computing the Sky at Extreme Scales".
In addition to astrophysics, Zarija's research included topics in applied nuclear physics. He published research on the practical use of cosmic rays to identify materials and remotely diagnose the state of damaged reactor cores in the wake of the 2011 Fukushima Daiichi Nuclear Power Plant accident.
