Research Interest:

    • Polymerization Kinetics: Modeling, Simulation of Polymer Reactors and Experimental Studies.
    • Process Control and Optimization: Chemical Reactors and Infra-red/Convective dryers.

Research Area:

The research activity currently undertaken focuses on developing mechanistic models in polymer reaction engineering with a particular emphasis on kinetic studies of polymerization systems using multifunctional initiators. The research involves experimental kinetic investigation of homo and co-polymerization systems. Depending their structure and functionality, some initiators may produce branched polymers. The presence of branching into the final polymer product can greatly influence a number of polymer properties from the solution to the melt state. In addition, infrared drying of some delicate materials such coating materials, fibers and polymer solutions is another research avenue of interest. Both infrared dryer and polymer reactors are highly nonlinear processes and require efficient control strategies such as nonlinear MPC control.
