Statistician & Data Analyst | R, Python, Biostatistics & Quantitative Modeling

Profile Summary

I help researchers and businesses turn complex datasets into clear, reproducible analyses. I hold an M.S. in Statistics and Data Science from the University of Wisconsin–Madison, with experience in biostatistical research and quantitative market-risk modeling. At UW–Madison, my research involved genetic association analysis, mixed-effects models, and meta-analysis. I worked with genomic datasets, prepared data for analysis, and created visualizations to communicate findings. During my market-risk internship at Freepoint Commodities, I developed and evaluated risk models for energy markets, including Value at Risk, GARCH, and EWMA approaches. My work included backtesting, sensitivity analysis, and explaining model assumptions and limitations. I can support projects involving: • Data cleaning, validation, and exploratory analysis • Regression and mixed-effects modeling • Biostatistical and genetic association analyses • Time-series analysis and risk-model evaluation • R and Python code development, debugging, and reproducible workflows • Statistical visualizations and clear interpretation of results I focus on understanding the research question, choosing appropriate methods, and delivering organized code, results, and explanations. I communicate in English and Mandarin Chinese.
