Research

The focus of my research is on creating and analyzing simulation-based decision-making algorithms and experiment designs, particularly under model risks. I explore both the theoretical foundations and practical applications of operations research and machine learning.

Below is a list of my articles. You can also find them on my Google Scholar profile.
