I am a second year Ph.D. student in the Computer Science Department at Carnegie Mellon University where I am fortunate to work with Rashmi Vinayak as part of the Parallel Data Lab.
My research interests broadly include in-memory caching, CDN caching, building high-performance systems with relaxed fault tolerance and duralbility.
Previously, I worked with Yao Yue at Twitter, Ymir Vigfusson at Emory University.
I also go by Jason, so feel free to call me Jason. My Chinese name is 杨骏骋.
