Hi there! I am Haoran Ye (叶皓然), a first-year AI Ph.D. student at Peking University, advised by Prof. Guojie Song and co-advised by Prof. Xin Zhang. Prior to that, I received my B.Eng. from Soochow University, where I had the honor to work closely with Prof. Zhiguang Cao, Prof. Helan Liang, and Prof. Yong Li. My current research interests include Human-Centered AI (incl. LLM psychology, LLM alignment, social computing) and learning to optimize (incl. neural combinatorial optimization, LLMs as hyperheuristics, deep evolutionary algorithms, EDA, etc.).
