About Me
I am a postdoctoral researcher in the Department of Computer Science at ETH Zurich, where I am fortunate to work with Dr. Ana Klimović as part of the Systems Group.
My research interests span storage systems, cloud systems, and data-center applications. The goal of my research is to improve the performance and resource efficiency of large-scale distributed systems.
I completed my Ph.D. in the Computer Science Department at Emory University, advised by Dr. Ymir Vigfusson. My dissertation was on conducting data-driven performance modeling in complex networked systems.
If you're interested in my research or just want to chat, feel free to reach out (yazzhang@ethz.ch). I'm always happy to help and connect.
