Big Data High Performance Computing

  Optimization Algorithm and Data Analysis

We conduct research mainly in the areas of optimization algorithms and data analysis. During these years, we have focused on some specific problems, including online selling, distributed message dissemination, multiple robots collaboration, community discovery and evolution in social networks, online frequency assignment, online code assignment, bin packing, scheduling, etc. We have undertaken 1 NSFC key project, 1 NSFC general project, 1 National Key Research and Development Plan, 1 Key Program of the Chinese Academy of Sciences and several Shenzhen research projects. In these years, we have published more than 100 research papers in some leading journals and conferences.

  Spatio-temporal data processing

Based on the spatiotemporal data collected by increasingly emerging sensors such as mobile phones, social media, and Internet of things as well as the high-performance computing technology, we focus on analyzing human spatiotemporal activity patterns in the information age, modeling spatiotemporal phenomena, and simulating spatiotemporal processes. Our research can help breakthrough the limitation of lacking large-scale human activity data sources for decades, and can offer critical methods and technologies for various application areas such as smart transportation, urban planning, public health, mobile Internet service, and big data service in a more general word.

  Computational Biology and Bioinformatics

Our research concentrates on big data analytics in bioinformatics and numerical simulation of molecular structure and properties. The research projects are mainly concerned with highly scalable genome assembly, metagenome-wide association study,protein structure prediction, protein folding simulation and molecular/medical image processing,etc. Research methods mainly include parallel computing, machine learning, stochastic and deterministic optimization. With the help of supercomputers and parallel computing, we have developed high-scalable gene sequence assembly software (SWAP-Assembler) to improve the efficiency of gene data analysis. Using machine learning and stochastic / deterministic optimization algorithms, we study characteristics of protein structures to improve the structure prediction accuracy for both globular and membrane proteins.
