Research Interests:

My research interests are in the areas of process control and optimization.

The objectives of the current research program are:

1. To develop tools of advanced processing (automation and optimization) for use in chemical, petroleum and electric power generating industries. Methods are being developed to determine the best operating conditions for chemical and biological reactors and to improve the control of chemical, petroleum, combustion and physical processes.
    
2. To promote the application of advanced process control and optimization technology in the above industries.
    
3. To train personnel in the development and application of the new methods.

The emphasis of our work is in the development of methods that are conceptually simple and easy to implement. This emphasis will help the user industry, especially small scale, to benefit from the advanced process control technology. This work is expected to result in: better yield in chemical, petroleum and biological processes, lowered emissions from wastewater treatment units, and enhanced contaminant removal in coal combustors. The work will thus help the industry to stay competitive in today’s global economy and to meet the environmental regulations.
