Research (By Topic)

My current research centers around (1) machine learning algorithms, (2) data-driven social good, and (3) the human-AI interface.

Machine Learning Algorithms


I primarily study the design and analysis of transfer learning and bandit algorithms for effective data-driven decision-making.
Applications include personalized healthcare, clinical trial designs, dynamic pricing and product recommendations.
