Hi there! I am Haoran Ye (ๅถ็็ถ), a first-year Ph.D. student at Peking University, advised by Prof. Guojie Song. 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 AI value modeling (incl. LLM psychology, LLM alignment, social computing) and learning to optimize (incl. neural combinatorial optimization, LLMs as hyperheuristics, deep evolutionary algorithms, EDA, etc.).
