Selected Publications

Note: In computer science, top-tier conferences are usually at least as important as top-tier journals. Most conferences are fairly competitive with rigorous reviews (3-8 reviews) and a very low acceptance rate (about 20%). The CCF has recommended some top-tier conferences and journals in different research areas (please see the CCF Website).  Our research is in the area of "Computer Architecture/Parallel and Distributed Computing/Storage System".
