Hi I'm Kexuan (Kiana) Sun!

I'm a first year CS PhD student at University of Southern California (USC), Information Sciences Institute. I am advised by Prof. Satish Kumar Thittamaranahalli. I completed my bachelor's degree in software engineering at Huazhong University of Science and Technology (China), and my master's degree in computer science at USC.

Research Interests

My interests are mainly on Knowledge Representation and Reasoning, Constraint Programming, and some other subfields of Artificial Intelligence (AI).
