During April 2025, Nam Pham developed and delivered the CO2_fundamental_PhamTsung.csv dataset for the FoleyLab/data_repository project, focusing on enabling reliable spectroscopy analysis. Nam applied data cleaning and standardization techniques to ensure high data quality, including precision normalization, consistent formatting, and the removal of an erroneous data point. Working primarily with CSV data, Nam maintained a clear and reproducible commit history to support auditability and downstream analysis. The work demonstrated a methodical approach to dataset creation and quality assurance, emphasizing reproducibility and traceability while addressing the specific needs of scientific data integrity within the context of spectroscopy research.
