Hi there, I’m Xinrui “Ryan” Jiang, a master’s student in EE at Stanford University. Prior to that, I received my B.Eng from Fudan University. During my undergraduate study, I was fortunate to be advised by Professor Zhengzhong Tu at Texas A&M University and Professor Berkin Bilgic at Martinos Center for Biomedical Imaging/Harvard Medical School.
My work focuses on generative AI, agentic AI, and low-level vision. I enjoy the process of formalizing complex real-world challenges into optimization problems, and deriving actionable solutions with data-driven computational methods.

- We present 4KAgent, an agentic image super-resolution generalist designed to universally upscale any image to 4K resolution, regardless of input type, degradation level, or domain.

- We purposed NLCG-Net, a model-based and data-driven framework achieved via self-supervised learning, which incorporates nonlinear conjugate gradient optimization and Neural Network Regularization in a iterative manner and achieves zero-shot quantitative MRI reconstruction. T1, T2 mapping results on phantom and in-vivo data demonstrates NLCG-Net’s superiority on estimation quality at high acceleration.
