Yuni Xia is an Associate Professor of the Computer and Information Science Department at Indiana University - Purdue University Indianapolis (IUPUI). She received PhD and MS in Computer Science from Purdue University, and B.S. in Computer Science from Central China (HuaZhong) University of Science and Technology. She worked at IBM T.J. Watson Research center in 2003.  Xia's research is on data mining and databases, focusing on mining and management of big data and data streams including biomedical data, sensor data and moving object data. She also works on managing uncertainty in the decision support process.

    Research Projects (we gratefully acknowledge the support of funding agencies):
    Health-Terrain: Visualizing Large Scale Health Data, Supported by US Department of the Army, Co-PI (PI: Fang)
    This project aims to design a framework and new techniques for mining and visualizing large scale health data.

    Development of Key Technologies for Big Data Analysis and Management Software Based on Next Generation Memory,  Supported by ETRI,  Co-PI (Institute PI: Lee)
    This collaborative project seeks to develop big-data main memory database management system and distributed streaming processing system using hardware acceleration techniques including FPGA ( programmable / reconfigurable chips) and GPGPU(general purpose graphics processing unit).       

    Large Scale Sensor Stream Analysis and Mining for Geriatric Care, Supported by IBM
    This project aims to design and develop a real-time distributed sensor stream monitoring and analysis system for geriatric care. This enables effective home-based continuous geriatrics care, which is not only cost-savings, but also improves the quality of life of the elderly and their families.

    DisProt Database: A Central Repository of Information on Intrinsically Disordered Proteins, Supported by NSF,  Co-PI (PI: Dunker)
    The goal of this project is to fully develop DisProt, a database that provides an essential depository of information about intrinsically disordered proteins (IDPs) . DisProt will be not only a collection of data on intrinsically disordered proteins and their functions, but also a unique research tool to conduct various computational studies on these proteins and to help design better research strategies for studying individual IDPs in laboratory. It's expected that DisProt will support a very wide-spread use, both for the purpose of carrying out bioinformatics experiments and for the entire community involved in understanding cell and molecular biology.

    TrafficAnalyzer: A Real-time Traffic Stream Processing and Analyzing System, Supported by IBM
    Modern traffic monitoring systems are required to perform real-time processing and analysis of peta-bit continuous data streams. In this project, we propose to design and develop a real-time traffic stream processing and analyzing system.  The most important feature of TrafficAnalyzer is the real-time performance. The results of processing need to be produced with virtually zero latency, because in traffic monitoring system, real-time response is crucial for reducing accident rate and smoothing traffic flow. TrafficAnalyzer must support sophisticated time-windowed processing operations since streaming data continually changes, often at high rates. These operations should be executed in a way that produces results incrementally as new data arrives, since the entire data set is never available in its entirety.  TrafficAnalyzer also provides careful management of the historical data, as it need compare and combine present data with the past to study the traffic flow change over the time. TrafficAnalyzer is also resilient to inaccuracy and uncertainties in the data streams, because inherent variations, losses, or reordering of the data streams cause data to arrive in the wrong order, or with variable delays.

    Development of SYMBIOTE; A Reconfigurable Logic Assisted Data Stream Management System for Multimedia Sensor Networks, Supported by NSF, Co-PI (PI: Lee)
    Numerous emerging applications require real-time processing of high bandwidth multimedia data streams. In this project, we propose a novel class of data stream management systems called Reconfigurable Logic Assisted DSMS (RLADSMS) that will provide one of the first comprehensive and demonstrative approaches to using Reconfigurable Logic coprocessors as data stream accelerators in the prototype RLADSMS called SYMBIOTE. This project will investigate key issues such as data models, query languages, hardware DSMS operators, corresponding cost models of query execution, considering hardware complexity of database operators, run-time complexity of hardware and software operators, interconnect latencies, bandwidth, resource allocation as well as optimization techniques for this new class of data stream management system.

    Invention of a Consumer-Side Geriatric Health Care Knowledge Management and Decision Support System, Supported by 21st Century Research and Development Fund,  State of Indiana, Co-PI (Institute PI: Palakal)
    This project proposes to build an innovative Knowledge Management system unique in the Geriatric Care Management Industry. This system will accelerate the adoption of standards of care and provide the accumulation of knowledge from current Social Science, Psychology, and Health disciplines. It will also build a basis, comparable to the Health Care Industry model, for evidence based outcomes validation.
