I am a Ph.D. candidate
in the Department of
Computer Science and Engineering at The Ohio
State University. I got my Bachelor Degree from International School of Software, Wuhan University, Wuhan, China. I work in the Data-Intensive
and High-Performance Computing group led by Dr. Gagan
My research has been focusing on building a light-weight data management layer over large-scale scientific data in distributed environments,
and addressing the challenges in effectively storing, managing, querying, disseminating, and analyzing big data
by diverse techniques, including MapReduce, online processing, approximate processing, various indexing and parallelization approaches.

New Open-Source Project: An in-Situ MApReduce liTe (Smart) for scientific analytics
- Smart can load data from distributed memory for in-situ processing and support two different in-situ modes -- time sharing and space sharing;
- Smart can minimize the modification of simulation code;
- Smart can meet strict memory bound of in-situ analytics by using alternate MapReduce API;
- Smart can launch execution from parallel simluation code region and still hide the paralleizaiton in a sequential programming view;
- Smart is written in C++11, and the implenetaiton follows Google's coding style.
