Research

The growing availability of individual-specific data has led to an exciting era of personalized decision-making: A paradigm that exploits the heterogeneity within populations to deliver tailored service decisions and achieve improved outcomes. This approach neccesitates learning from data to determine optimal actions and timing, dynamically adapting to the evolving conditions of each subject (e.g., a patient requiring treatment or a high-tech system requiring maintenance). 

My research focuses on advancing personalized decision-making by leveraging tools from operations research, statistics, and machine learning, with applications in the maintenance of high-tech systems and healthcare operations.
