About me
I am now a research assistant with Software Institute at Nanjing University.
I received the B.S. and Ph.D. degrees in computer science and technology
from Nanjing University in 2009 and 2016, respectively.
From 2017-01 to 2020-07, I was a research assistant
with the Department of Computer Science and Technology at Nanjing University.
My research interests include Distributed Computing and Formal Methods. <<more>>
