Yuxi Fu

I am a professor of the Department of Computer Science, Shanghai Jiaotong University (SJTU). I served as the chair of the department from February 1999 to May 2009. Currently I am serving as the dean of the School of Software. I am the director of BASICS, the Laboratory for the Basic Studies in Computing Science, and the director of the MoE-MS Joint Key Laboratory on Intelligent Computing and Intelligent Systems.

My research interest has been mainly in theoretical computer science. The evolution of my research interest, from type theory and its semantics, to process theory, and then to the expressiveness of interaction, can be seen from the list of my publications. My current research focuses on theory of interaction.

The theory of interaction aims to provide a unified treatment to both computation models and interaction models. The starting point of the theory is to define, in a model independent manner, the two most important relationships in computer science, the expressiveness relationship between the models and the equality relationship between the objects of a model. The model independence is crucial in order to formalize the foundational postulates of computer science. The principles and the methodologies of the theory of interaction cast new lights on complete models such as the name-passing calculi and the value-passing calculi.

I am an executive member of the Asian Association for Foundation of Software (AAFS).

I am on the editorial board of Mathematical Structures in Computer Science.

I am on the programme committee of WoLLIC 2012.

I teach computability course and computing theory course.
