Ph.D., Industrial & Operations Engineering, University of Michigan, 2023M.S., Statistics, University of Michigan, 2023M.S., Industrial Management Engineering, Korea University, 2018B.S., Industrial Management Engineering, Korea University, 2016

My research focuses on the Internet of Things (IoT)-enabled systems, where multiple entities/units (e.g., vehicles, wearable devices, etc.) collect data and collaborate to establish enhanced smart analytics based on their connectivity. I enjoy exploring data-driven methods such as federated learning, multi-task learning, and Bayesian probabilistic modeling, to tackle key challenges arising in data analytics for connected systems, including statistical/systems heterogeneity, fast personalization, and inscalability. As such, I aim to advance smart & connected healthcare and manufacturing systems and their reliability.
