Dr. Nong Ye is a Professor of Industrial Engineering at Arizona State University (ASU), Tempe, Arizona. Dr. Ye received her Ph.D. degree (1991) in Industrial Engineering from Purdue University, West Lafayette, Indiana, and her M.S. degree (1988) and B.S. degree (1985) in Computer Science from the Chinese Academy of Sciences and Peking University in P. R. China, respectively.

Dr. Ye's past and current research activities, which have received over $8M external funding support and have produced seventy-six journal papers and three books (including Secure Computer and Network Systems: Modeling, Analysis and Design and The Handbook of Data Mining), fall into the following two areas.

·        Data and knowledge exploration, involving the following data and applications.

o       Computer and network data for real-time decision making to detect and assess cyber attacks and security risks on computer and network systems. Through data mining, statistical analysis and data modeling, attack-sensitive data variables are selected, statistical and mathematical features of data are extracted and examined to discover distinctive univariate and multivariate characteristics of cyber attack data, data models are defined to represent discovered data characteristics, and detection and assessment algorithms which incorporate data models are developed.

Two examples of sponsored research projects:

Two examples of publications:

§         N. Ye, Q. Chen, and C. Borror, “EWMA forecast of normal system activity for computer intrusion detection.” IEEE Transactions on Reliability, Vol. 53, No. 4, 2004, pp. 557-566.

o       Cognitive behavioral data for human-computer interface design. Through experimental design, statistical hypothesis testing and data mining, human behavioral and performance data in computer programming and manufacturing assembly tasks are collected and analyzed to understand expert-novice differences in knowledge representation which are then used to design user-friendly computer interface.

Two examples of sponsored research projects:

§         N. Ye, “The MDS-ANAVA technique for assessing knowledge representation differences between skill groups.” IEEE Transactions on Systems, Man and Cybernetics, Vol. 28, No. 5, 1998, pp. 586-600.

o       Biomedical data for brain science with applications in Brain-Machine Interface (BMI) for assisting people who have lost motor or sensory function and in prediction and treatment of brain-related diseases such as the Alzheimer disease and brain tumors. Through data mining, statistical analysis and data modeling, brain data (including electrical spike waveforms and structural/functional images) are analyzed to discover statistical/mathematical features and characteristics of brain neuron population dynamics, and data models are defined accordingly and employed in applications for BMI and disease prediction/treatment.

One example of sponsored research:

§         Ira A. Fulton School of Engineering, February 2007 - February 2009, N. Ye (Director), "Cluster of Data Exploration and Modeling for Brain Science."

o       Urban system and environment data for urban system sustainability. Through data mining, statistical analysis and data modeling, urban metabolic flow data (including data about water, materials, energy, waste, air quality, etc.) are analyzed to understand interrelationships of urban systems and to design sustainable urban system infrastructures.

·        Optimization and quality control of system process and operations, involving the following systems.

o       Computer and network systems for dependability, especially service stability and end-to-end delay guarantee. Though modeling, simulation and optimization of job scheduling, admission control and resource reservation, job waiting time variance is minimized at local and regional levels of computer and network services, and end-to-end delay guarantee is enabled at the global level of computer and network services.
