Research
SPSA - Optimized Ranker Ensemble for Movie Recommendations
Advisor: Serin Hong
-
Designed and implemented a movie recommender algorithm that directly optimizes top-K quality using Simultaneous Perturbation Stochastic Approximation (SPSA)
-
Benchmarked standard recommenders with HitRate@K on 200k+ users (32M+ ratings); validated with user-level paired bootstrap.
Python Package Development for POMP Models
Advisor: Edward Ionides
-
Implemented Monte Carlo-Adjusted Profile Likelihood (MCAP) for pypomp, a JAX based Python package for inference on partially observed Markov process (POMP) models, constructing profile-likelihood confidence intervals that separate statistical and Monte-Carlo error, enabling reliable uncertainty quantification for stochastic, simulation-based inference.
Hyperbolicity of Fine Arc Graphs
Advisor: Roberta Shapiro
-
Conducted in-depth study of geometric group theory and topological graph structures to investigate the hyperbolicity of fine arc graphs on compact orientable surfaces.
-
Developed a proof outline, using surgery arguments and quasi-isometry frameworks.
Evaluating DEI Impact Using Synthetic Control Method
Advisor: Yuekai Sun
-
Conducted a causal inference study to evaluate the impact of the University of Michigan’s Diversity, Equity, and Inclusion (DEI) program using the Synthetic Control Method.
-
Demonstrated robust positive treatment effects for DEI across racial and economic access metrics, reinforcing causal links between policy implementation and improved student equity outcomes.
Undergraduate Honors Thesis
Advisor: Edward Ionides
-
Validated and debugged pypomp using the Heston stochastic volatility model under JAX, which was for Thesis, Testing a Modern Inference Framework for POMP Models: A Case Study Using Stochastic Volatility
-
Designed Monte Carlo experiments and diagnostic tools to compare pypomp against R’s pomp, ensuring correctness and reproducibility.
