Biography

Yongle Zhang is a tenure-track assistant professor in the Computer Science Department at Purdue University. He received his Ph.D. from the University of Toronto working with Dr. Ding Yuan. He was recommended to Institute of Computing Technologies for Master’s program after he received his Bachelor’s degree from Shandong University.

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

I am looking for highly motivated students at different levels (research intern, master, PhD) to work with me in software systems. If you are interested, please contact me with your resume and transcripts.

Research

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.
