INTERNATIONAL COLLABORATIVE RESEARCH
The European Organization for Nuclear Research (CERN), LHCb collaboration, France and Switzerland. (2011-2012)
Software Package Development (C++ and Python)
Independently developed and implemented a novel approach to measure detector tracking efficiencies, denoted as “partial and full” method, where the efficiency is extracted from the ratio of full and partial reconstruction of D^(*+) decay sequence with one track ignored in the latter case. The design consists of two major packages: one provides the user interface to the information of the full reconstruction and the other one performs the kinematic fitting utility on a tuple-based data structure. Physics properties of the missing track are inferred and optimized by kinematic fitting using “Lagrange multiplier” method. This is pioneering work in LHCb collaboration on tracking efficiency estimation which requires profound knowledge of physics, statistics and software engineering skills. The asymmetry between detection efficiency of positively and negatively charged track is determined at 0.18% level of precision. After being incorporated into LHCb software framework this tool has been used by many LHCb analyses now .
Developed specific GUI system for experimental data quality monitoring in order to study the radiation damage effects of n-on-n sensors in VELO subdetector. Also in charge of code maintenance for this particular package.
Physics Analyses (C and C++)
Performed analysis for the measurement of semileptonic CP violating asymmetry a_sl in B ̅_s decays, which is one of the major physics program in LHCb, the result is very consistent with the Standard Model. I implemented independently the whole analysis which was chosen as the baseline for publication  and developed a new calibration algorithm for muon trigger and identification efficiencies which minimizes the bias from the trigger system. Also developed an algorithm to emulate the muon hardware trigger threshold by doing a lookup table search.
Performed analysis for the measurement of D_s^+-D_s^- production asymmetry  which is a litmus test for “partial and full” method of pion detection efficiencies and milestone towards the a_sl measurement. This result can constrain future models of heavy flavor production.
Performed analysis for the measurement of form factors in Λ_b→Λ_c μν semileptonic decays.
Performed analysis for the measurement of B hadron fractions using semileptonic B decays. 
BEAM TEST DATA ANALYSES
Syracuse University (2009-2011)
Analyzed testbeam data to characterize Timepix hybrid pixel detector (C++): (a) built comprehensive software framework which allows efficient object instantiation such as pixel clustering, pattern recognition, and particle track fitting. Unbiased spatial resolution of 4.0±0.1 μm for angled tracks and 4.4-11 μm for perpendicular tracks were achieved for DUT (b) a charge calibration method developed allowing a precise measure of the true deposited charge with predicated response function called for each of the 64k pixel cells (c) Landau distribution study: different models such as Bichsel approach, Blunck-Leisegang function implemented to study both MPV and the broadening effects due to atomic binning, electric noise and gain calibration etc.
