Yuni Xia is an Assistant Professor of the Computer and Information Science Department at Indiana University - Purdue University Indianapolis (IUPUI). She received the B.S. in Computer Science from Huazhong University of Science and Technology in China in 1996, and her MS and PhD in Computer Science from Purdue University in 2002 and 2005. She had worked as a research intern at IBM T.J. Watson Research Center.

Xia's research is on data mining and databases, focusing on mining and management of uncertain data and constantly evolving data such as sensor data and moving object data. She also works on data storage, retrieval, management and mining in data-intensive applications, and managing uncertainty in the decision support process.  Her research is supported by National Science Foundation, State of Indiana and IBM. She is a recipient of IBM Real Time Innovation Award in 2008.
