Large scale simulations, Data management, Data Visualization

Simulation Excellence: Conducted extensive linear and nonlinear simulations with over 4M core hours
Data Standardization: Addressed inconsistencies data by developing robust pre-processing tools.
Post-Simulation Data Extraction: Designed and refined an extensive suite of post-processing tools; handled vast data sets, with individual simulations generating data up to 30TB.
Experimental Diagnostic Replication: Innovated a synthetic diagnostic tool mirroring experimental apparatus, strengthening the bridge between simulated outcomes and real-world results.
Academic Contribution: The research were encapsulated in 4 published journal articles, 1 invited talk

A reduced model SLiM and Graphic User Interface (GUI) for such model

Decade-long Mystery Solved: Developed the pioneering SLiM model using kinetic global theory for microtearing modes (MTM); the first-ever global MTM model that successfully demystified a decade-long unresolved phenomenon. This work is underscored by 4 journal publications and recognition in 2 invited talks.
Optimization Mastery: Enhanced simulation speeds by a factor of 100 utilizing both GPU and CPU resources. Additional structural optimization strategies yielded even greater computational acceleration.
Parallel Computing Achievement: Implemented parallel code suitable for the national computational center, a feat that would otherwise necessitate a staggering 15 years on a conventional PC.

Neutron electron dipole moment (nEDM) experiment

Tested high power (3Watt) infrared laser and mounted for the polarized Helium 3.
Designed and constructed a polarimeter using a surface mount high gain op-amp, a low noise environment is needed for a useable signal-noise ratio. The printed circuit board (PCB) was designed using KiCAD with reducing cross talk and impedance in mind.
Designed and printed the mounts for the optics and circuits by the 3D printer using Sketchup. All the optics and the circuits are placed in the metal box to be shielded from the high-intensity radio-frequency wave which will be turned on during the experiment.

Monte Carlo study of Quark-Gluon Plasma using photon jet observables

The lead (Pb) lead collision creates the heated quark-gluon plasma that provides insight into the early stage after the Big Bang.
Performed Monte Carlo simulations using PYTHIA and JEWEL to compare with the Pb-Pb collision at 2.8TeV conducted in the European Organization for Nuclear Research (CERN) A prediction was made on 5TeV collision for the future experiments. the results have been presented in a poster at the American Physical Society (APS) Division of Nuclear Physics (DNP) annual meeting.
Managed the dataset using ROOT to visualize the ratio of the photon and jet momentum to be compared to the experiment.
