Research Interests:

    Starting from nuclear and particle physics, my research interest evolved into astroparticle physics in late 1990's, with focus on high energy cosmic rays, muons in cosmic ray showers, high energy neutrino astronomy, direct dark matter search, radiological and airborne contamination control. I have worked for about 10 years as a research scientist at Bartol Research Institute and the University of Delaware on high-energy cosmic ray and neutrino astronomy projects SPASE-II/AMANDA/IceCube. I joined SDSM&T in 2009 to initiate research and education programs in particle/astroparticle physics. I am currently also working on the direct dark matter search experiment Large Underground Xenon (LUX) experiment and the LZ project. My involvement in the long-baseline neutrino project LBNE/DUNE started in 2010 and was passed over to new faculty members in the department in 2015.

    The links to those projects are:
  • IceCube: High Energy Neutrino Astronomy at the South Pole, Antarctica AMANDA/SPASE/RICE South-Pole winter-over scientist 1998 - 1999, member 2002 - 2009, IceCube Publication Committee member 2007 - 2010, associate member 2010 - 2014, full member and IB member for SDSMT since 2014.
    • Currently working on 3-D reconstruction of high energy cosmic rays, prompt signals through muons, etc.
  • LUX/LZ Dark Matter Search Experiment in Sanford Lab, Homestake Lead, SD LUX member & Executive Committee member since 2009; LZ member since 2012, institutional representative 2012 - 2015.
    • Currently working on the data from the veto/shielding system and the coincident events between the veto/shielding system and the two-phase Xenon TPC.
  • The Long-Baseline Neutrino Experiment: LBNE, LBNF/DUNE Member since 2010, Radiological & Cleanliness Convenor 2012 - 2014, institutional representative 2010 - 2015.
