Welcome!
I am Yiyang Chang, currently working as a Researcher in System and Networking at Bytedance Inc, Seattle. I received my Ph.D. from School of Electrical and Computer Engineering at Purdue University. Boiler up! My Ph.D. advisor is Prof. Sanjay Rao. Prior to that, I received my B.S. from School of EECS at Peking University in Beijing, China.
My research interests lie in Computer Systems and Networking. I have been working on traffic engineering, network validation and synthesis, cloud computing, and distributed SDN controller design. My Ph.D. dissertation is about formally validating network designs to meet performance requirements under failures.
