M.S. in Biostatistics (Data Science Track) at Yale University

I am a Master’s student in Biostatistics (Data Science track) at Yale University, where I work with Dr. Yize Zhao at the Yale School of Public Health. I earned my Honor B.S. in Computer Science and Statistics (with high distinction, minor in Mathematics) at the University of Toronto. My research lies at the intersection of machine learning, statistical modeling, and large-scale, multi-modal complex data. I develop interpretable and scalable statistical and machine-learning methods for high-dimensional and structured data, with particular interests in Bayesian modeling, statistical neuroimaging and brain connectivity, disease-network and hypergraph modeling for longitudinal health data(EHR), multilingual NLP and LLM evaluation, and large-scale retrieval systems(RAG).
