🙋‍♂ About

I am a Research Engineer in the Department of Industrial Systems Engineering and Management at the ​​National University of Singapore​, advised by Dr. Nan Chen. My research interests include functional data analysis, tensor decomposition, Gaussian process, state space model, and Bayesian network in the areas of advanced manufacturing and medical testing. I have published papers or received major revisions at top-tier international journals in the fields of Quality, Statistics & Reliability, such as Technometrics, IISE Transactions, Journal of Quality Technology, IEEE Transactions on Knowledge and Data Engineering (Google Scholar). My research has been recognized with several prestigious awards, including ICQSR, INFORMS-DMDA, INFORMS-QSR, IISE-QCRE, and QRSE.

I am actively seeking a position as a tenure-tracked Assistant Professor in 2025. If you have any information, please contact me!
