Lihan Hu (胡砺寒)

I am a fourth-year Ph.D. student in the Computer Science Department at the University of Iowa and advised by Dr. Peng Jiang. I am a member of Parallel Group. Before coming to UIowa, I received my Master's degree (Sep.2019-Jun.2022, major: Pattern Recognition and Intelligent System) at Hohai University, Nanjing and advised by Prof. Lixin Han. I worked closely with Prof. Hong Yan at the City University of Hong Kong from Sep.2020-Oct.2021. I received my Bachelor's degree (Sep.2014-Jun.2018, major: Computer Science) at Nanjing Audit University, Nanjing. I am looking for Summer 2026 Research Scientist/Research Engineer internship. If you are interested in me and my research, please feel free to contact me via email.
