I am always looking for self motivated students at different levels (research intern, master, PhD) to work with me in software systems. If you’re interested in working with me soon, please feel free to contact me with your resume and transcripts. If you are interested in joining my research group as a graduate student, please follow the steps on Application Steps and Process and mention my name. We accept application for both Spring and Fall semesters.


I am a tenure-track assistant professor in the Computer Science Department at Purdue University. I obtained Ph.D. at the Department of Electrical and Computer Engineering, University of Toronto. I am very fortunate to work with my advisor Professor Ding Yuan. I was recommended to Institute of Computing Technologies, Chinese Academy of Sciences for Master's degree after I obtained my Bachelor’s degree at Shandong University. I spent a happy five months at City University of Hong Kong as an exchange student.

My Chinese given name is 永乐(Yong Le), pronounced as 永/juŋ/ 乐/lə/.


My research interest is in systems software with a focus on improving the reliability and availability of complex, real-world systems. In particular, we are currently working on cutting-edge tools that help developers with failure detection and diagnosis in production cloud systems, as well as design and implementation of diagnosable software systems.
