Xinheng "Asher" Ding | 丁欣恒

Hi, I am currently a Ph.D. student in Computer Science at the University of Minnesota Twin Cities, fortunate to work with my awesome advisor, Dr. Zirui "Ray" Liu.

From August 2024 to July 2025, I spent a year as a Computer Engineering Ph.D. student at Indiana University Bloomington, where I was supervised by Dr. Dingwen Tao and Dr. Fengguang Song. Prior to that, I received my Bachelor’s degree in Engineering from the Department of Automation at the University of Science and Technology of China (USTC).

🎯 I am striving to grow into a professional, active, and influential researcher. If you have any suggestions, comments, critiques, encouragement, or collaboration opportunities, feel free to share them with me—I would greatly appreciate it.(^_^)
