Dr. Oleksandr Burlayenko

- Supervised courses for BSc/MSc students. - Led analyst in ttbar spin correlation and quantum entanglement research: developed analysis strategy, reduced measurement uncertainty by up to 92% (excl. per selection). - Developed and optimized production code for data sample simulations. - Managed big-data processing on the WLCG & NEMO clusters. - Neural network model tuning, improving sample purity by 32% and efficiency by 11%. - Implemented profile likelihood fits for parameters extraction.

- Collaborated across Particle Modeling, Jet/ETmiss, and Top-Properties groups to enhance model accuracy. - Model code-development, production, and physics-validation of Monte Carlo (MC) samples for particle modeling. - Assessed the impact of various nuisance parameters on new MC samples. - Designed the intercalibration corrections in large-scale data analysis for improved precision modeling (paper in progress). - Regularly presented progress in CERN meetings and international conferences.
