My main research interests include:

**Intelligent systems and control**(Development of novel computational intelligence and machine learning techniques, such as fuzzy systems, artificial neural networks and evolutionary multi-objective optimization): In this area I focus on computational intelligence based modeling and control techniques (e.g., adaptive fuzzy systems, multi-objective evolutionary algorithms, granular computing, recurrent neural networks, etc.) and their applications in various real-world engineering, biomedical and business problems (e.g., automatic train control, structural vibration control, optimum design and processing of metals/alloys, biomedical signal processing, computational neuro-ergonomics, retail supply chain forecasting and optimization, etc.).**Data science and engineering**(complex data mining and knowledge discovery: regression, classification and clustering): This area is concerned with construction of data-driven model from large-scale data. I have proposed advanced machine learning algorithms (deep learning, unsupervised learning, semi-supervised learning, ensemble learning, transfer learning, extreme learning machine, dynamical/adaptive machine learning, etc.) and apply them to identify and predict complex nonlinear phenomenon or mechanisms underlying big data.**Modeling, analysis, and control of complex biomedical systems**(brain signal processing, neuroergonomics, human-machine hybrid intelligence, brain-machine interaction): In this area I have concentrated on advanced modeling, analysis, optimization, and control theory and algorithms of complex biomedical systems.

**PRINCIPAL RESEARCH CONTRIBUTIONS**

My core research expertise is in computational intelligence, machine learning, human-machine hybrid intelligence, neurocomputing and neuroengineering. I have produced 68 referred journal publications, 14 books and book chapters, and 68 referred conference papers. For a list of publications, please visit my Google Scholar profile.

My significant research contributions include:

**1) Intelligent techniques for industrial control systems**

- Developed a long-range predictive control method for automatic train stopping (ATS) using an associative memory type neural network based on discrete Tayler series.
- Proposed a new fuzzy predictive control method for automatic train operation (ATO).
- Developed a nonlinear decentralized robust control scheme for active vibration control of high-rise structures. The results showed that the proposed control scheme not only can significantly reduce the structural response under the excitation of seismic wave or strong wind, but also is robust w.r.t. hardware failures.

**2) Combination of conventional and intelligent techniques for big data analysis**

- Developed an internal model based adaptive Kalman filtering (IMAKF) technique to filter the GPS-measured vehicular position and velocity data.
- Proposed a wavelet-based optimal denoising algorithm with high time-frequency resolution without using statistical assumptions about the signal and noise.
- Developed new time series forecasting methods, based on an adaptive regularization network and a nonlinear adaptive fuzzy approximator, for single-trial estimation of cerebral evoked potentials.
- Developed and applied adaptive machine learning and evolutionary multi-objective optimization algorithms to retail supply chain system modeling and optimization.

**3) Adaptive multi-modal human-machine systems and brain-machine interfaces**

- Developed an adaptive fuzzy system technique for accurate modeling and classification of Operator Functional State (OFS), Mental WorkLoad (MWL), and Cognitive Task-Load (CTL) of human operators based on the measured physiological data (e.g., neurophysiological and cardiovascular data). The work paves the way for preventing operator performance degradation or breakdown in safety-critical human-machine systems, which are ubiquitous in such domains as manned spacecraft, UAVs, air traffic control, nuclear power plant, and intelligent transportation systems.
- Designed an adaptive human-machine cooperative control system.
