Summary

I have built a strong foundation in both frequentist and Bayesian statistics through my work in a Bayesian statistics lab, where I studied essential Bayesian methods in depth and authored a research paper analyzing COPD patient data using Bayesian network analysis. In a data competition, I managed data preprocessing, conducted exploratory data analysis, and developed actionable insights that guided the team toward data-driven conclusions—most notably by participating in contests such as the Employment & Labor Public Data Utilization Contest and the Pharmaceutical Data Analysis & Utilization Contest, which challenged us to develop innovative solutions to social issues and improve operational workflows. I have extensive experience analyzing data using R, and I also utilize Python for implementing machine learning techniques such as XGBoost and applying SMOTE, while having a basic understanding of SAS. My roles as a Teaching Assistant and work-study student in the Business School Administrative Office have further honed my communication and teamwork skills, which are vital for bridging diverse methodological perspectives within team settings. Currently, I am contributing to a project in my physician father's lab focused on immune cell classification through FACS imaging. Additionally, I hold a TOEFL score of 100, underscoring my strong command of the English language.
