I'm Lei Zhang, a 4th year computer science PhD student in Department of Computer Science , Emory University , advised by Prof. Ymir Vigfusson. My research interest is on building and analyzing distributed systems, operating systems and storage systems. Generally, I love to find out real world problems on distributed memory, cache, and storage systems, achieve analysis, and build smart systems to solve them.

I got my bachelor degree in Computer Science and Technology from Tsinghua University, and master degree in Computer Science from Georgia Tech. I was once a PhD student at Georgia Tech, working with Prof. Karsten Schwan (passed away at 2015) and Prof. Doug Blough. After that, I transferred to Emory University in 2018.
