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 sequential decision-making algorithms for effective data-driven decision-making.
