Zarija Lukić is a research scientist in the Computational Cosmology Center.  He earned astrophysics Ph.D. in 2008 at the University of Illinois at Urbana-Champaign, and was postdoctoral researcher in the Theoretical Division of Los Alamos National Laboratory (2008-2011), and Computational Research Division of Lawrence Berkeley Lab (2011-2013).

Zarija's research combines (astro)physics and high-performance computing and he has published research articles in both physics and computational science venues.  Main topic of his research is the formation of structure in the Universe, and different ways of determining cosmological parameters from sky surveys.  His studies include modeling the Lyman-alpha absorption observed in spectra of distant quasars, evolution and properties of clusters of galaxies, internal structure and statistical properties of dark matter halos, and others.  He is a member of Dark Energy Spectroscopic Instrument (DESI) and Large Synoptic Survey Telescope (LSST) collaborations where he is engaged in simulation working groups.  Essential part of Zarija's research is finding new computational algorithms for modeling physical systems and building simulation codes which can efficiently run on largest supercomputers.  He was contributor to FLASH and HACC codes (2 times Gordon Bell finalist), and is one of core authors of multi-physics Nyx code used for intergalactic medium studies.  Over the past 15+ years, he utilized many leading machines at different supercomputer centers, including NERSC, National Center for Supercomputing Applications (NCSA), Los Alamos Supercomputer Center and Oak Ridge Leadership Computing Facility (OLCF), and has been the PI and co-PI on some of the largest computing allocations in the US.

In addition to cosmology, Zarija's research also includes topics in applied nuclear physics, and he has published research on the practical usage of cosmic rays to obtain material identification, and to remotely diagnose the state of damaged cores in Fukushima reactors.
