Biography

Qiuyi Wu is a postdoc research fellow in the Departments of Biostatistics & Bioinformatics at Duke University working with Prof. Anru Zhang. She received her Ph.D. from the Department of Biostatistics & Computational Biology at University of Rochester under the supervision of Prof. Xing Qiu in 2024. Her research interests include functional data analysis, image processing and high dimensional data anlaysis. Her thesis research attempts to bridge the gap between mathematics and statistics by applying mathematical techniques in novel ways to solve statistical problems. For her thesis work, she has developed a new kernel smoothing-finite element method (FEM) which applies the FEM method for discretizing partial differential equations to kernel smoothing tasks. The new method is designed to ensure efficiency and stability in high-dimensional scenarios. The primary applications for her work are in image processing and denoising tasks, which play an essential role in neuroimaging studies.
