Haiyun Guo

I am currently a 4th-year Ph.D. in the Depoartment of Electrical and Computer Engineering at Rice University, supervised by Prof. Ashok Veeraraghavan of Rice Computational Imaging Lab. Previously, I obtained my Bachelor degree from Huazhong University of Science and Technology. I work on computational photography and optical imaging, focusing on end-to-end learning, physics-based neural networks and optimization algorithms.   I am actively looking for research internships for 2025.
