Biography
Ruoqing Zhu completed his Ph.D. in Biostatistics from the University of North Carolina, Chapel Hill in 2013. From 2013 to 2015, he worked as a Postdoctoral Associate in the Department of Biostatistics at Yale University. He joined the Department of Statistics at UIUC in 2015. Besides this primary appointment, he is an inaugural member of the new "Engineering-Based" Carle Illinois College of Medicine. He was a Faculty Fellow at the National Center for Supercomputing Applications and affiliated with the Center for Genomic Diagnostics and the Personalized Nutrition Initiative at the Carl R. Woese Institute for Genomic Biology. He is also an Advisory Board member of Prenosis Inc.
Research Interests
I have a broad interest in developing statistical methodology, theory, and computational algorithms for decision-making problems, particularly in personalized medicine and reinforcement learning. Many existing models are rejected by practitioners due to unrealistic assumptions, unstable performance, lack of interpretability, and challenges posed by small sample sizes, high dimensionality, and complex data structures. Addressing these issues is both a challenging and exciting task in statistical research. My recent work focuses on uncertainty quantification, distributional shift, casual inference, and trustworthiness, aiming to develop more reliable and practical solutions for real-world applications. In addition, I have a strong interest in classical statistical learning and machine learning methods, including random forests, sufficient dimension reduction, and survival analysis, with applications in bioinformatics, infectious diseases, and nutrition studies.
