Biography

I obtained my B.S. degree from PKU in 2016, and studied as a master for two years. Development and optimization of graph database system gStore is my main work in this period. Currently, I am completing a Ph.D in computer science. To open a new area in my lab, I learn GPU programming and conduct the research independently. My research interests include database optimization, GPU computing and graph algorithms.
