Yuanyuan is currently a Research Staff Member at IBM Almaden Research Center. She received her PhD degree in Computer Science & Engineering in 2008 and MS degree in Computer Science & Engineering in 2005 both from University of Michigan, and BS degree in Computer Science & Technology with honor in 2003 from Peking University.

Current Research

Graph Analytics: Yuanyuan has long standing interests in graph analytics. Her current research includes building distributed graph-processing systems, designing distributed graph algorithms, and social network analysis. Her PhD thesis is on querying graph databases. The tools produced from her research have been widely applied in the National Center for Integrative Biomedical Informatics (NCIBI).
Graph Processing/Databases Papers: Giraph++ (PVLDB'13), Graph Summarization (ICDE'11 & SIGMOD'08), TALE (ICDE'08), SAGA (Bioinformatics'07)
Social Network Analysis Papers: Topic-Specific Influence (WSDM'14), Event-Based Social Network (SIGKDD'12).

Big Data Processing: Yuanyuan has studied efficient join algorithms for log processing on MapReduce, co-location of data on HDFS to speedup joins and group-by operations, and how to efficiently join data from heterogeneous environments (e.g. join data from a parallel db with data from a hadoop cluster).
Selected Papers: CoHadoop (PVLDB'11), MapReduce Joins (SIGMOD'10)

Large-Scale Machine Learning: Yuanyuan is the co-inventor and a lead contributor of a large-scale machine learning platform, called SystemML. In SystemML, machine learning algorithms are expressed in a high-level language, and then automatically compiled and optimized into a set of efficient MapReduce jobs on a cluster of machines.
Selected Papers: ParFor in SystemML (PVLDB'14), Numerical Stability in SystemML (ICDE'12), SystemML Archtecture (ICDE'11).
