Development of Liquid Argon Purification System for Neutrino Research
My senior honors thesis focuses on hands-on work to design and engineer the purifier and data analysis to assess its purifying performance using a homemade purity monitor. We built the Liquid Argon purifier and performed the regeneration process, a chemical reaction to activate water and oxygen reduction agents. The experimental setup was fine-tuned for optimized regeneration parameters, and initial data on removing oxygen and water contaminants have been collected.
My main contributions are designing and engineering the apparatus, and developing the graphical user interface (GUI) for real-time data visualization, available on GitHub Here.
I am working on the purifier data analysis using measured water vapor concentration to verify the regeneration process. Moving forward, my focus will be on completing and optimizing the database for the slow-control system. I will develop a data analysis pipeline electron drift lifetime measurement and purity analysis.
This involves further enhancing the remote monitoring system, integrating data from all sensors in the lab for seamless operation, and upscaling the apparatus for further Q-pix operations.

Quality assurance of Macro-Pixel Sub-Assemblies (MaPSA) before installation in CMS
Advisor: Dr. Jennet Dickinson, Fermilab
The High Luminosity upgrade for CERN's LHC will replace CMS silicon tracking detectors with PS modules featuring the Macro-Pixel Sub-Assembly (MaPSA). I developed database system for MaPSA quality assurance, enabling performance tracking of each MaPSA's pixel through an accessible database before installation into the CMS outer tracker.
Development of a Small-Scale Liquid Argon Purification System for Neutrino Research
Advisor: Dr. James Battat, Wellesley College
We developed a small-scale LAr purification system for neutrino detection, using active copper and molecular sieves to eliminate oxygen and water, ensuring low contaminant levels. I constructed the apparatus, developed data acquisition software, and ran the regeneration process to prepare the purifier.
