Bio

Yuni Xia is an Assistant Professor of the Computer and Information Science Department at Indiana University - Purdue University Indianapolis (IUPUI). She received B.S. in Computer Science from Huazhong University of Science and Technology in China, and her MS and PhD in Computer Science from Purdue University. 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, IBM and State of Indiana. She received from IBM the Real Time Innovation Award in 2008 and the Scalable Data Analytics Innovation Award in 2010.

        Databases: Constant Evolving Data Management, Sensor and Moving Object Databases, Data Uncertainty Management

    Current Research Projects:

1. Large Scale Sensor Stream Analysis and Mining for Geriatric Care, Supported by IBM.
Many countries face the problem of population aging. According to U.S.Census, the population of seniors in the United States will be 71.5 Million by 2030 - more than doubling in just 30 years [1]. While it is evident that the demand for medical care specific to this age group will increase, the number of physicians and nurses skilled and specialized in geriatric medicine is predicted to fall far short of the need. Furthermore, geriatrics care giving has an enormous economic impact. There is a growing need of using advanced technology to provide high-quality geriatric care at a reduced cost. The recent advance is wireless sensor technology suggests low-cost alternative for caring the elderly[3]. We plan to design and develop a real-time distributed sensor stream monitoring and analysis system for geriatric care. Medical sensors such as vital sign sensors, continuous glucose sensors, electrocardiograph sensors will be used to continuously monitoring the conditions of patients.  Environmental sensors, such as motion sensor and location sensors will be used to monitor the daily activities for patients as necessary, especially those with certain degree of physical or mental deterioration. The continuous sensor data stream will be automatically analyzed. In case of an emergency, an alarm will be sent to the urgent care and the patient family. 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.

2. DisProt Database: A Central Repository of Information on Intrinsically Disordered Proteins, Supported by NSF, Co-PI,  2009-2012
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.

3.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 accidences 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.

4. Development of SYMBIOTE; A Reconfigurable Logic Assisted Data Stream Management System for Multimedia Sensor Networks, Supported by NSF, Co-PI,  2008-2011
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 systems

5. 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,  2008-2010
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.
