Research

Dr. Gatzke's research interests are in the area of process modeling, control, and optimization. Efficient operation of chemical processes requires a fundamental understanding of dynamic and nonlinear characteristics. A variety of controller formulations can be developed to reduce product variability and improve productivity. Estimation and diagnostic methods can be used to develop process information that cannot easily be directly acquired by instrumentation. Recently, new moving horizon formulations involving unknown values taking discrete values have been proposed. These applications require online solution to constrained mixed-integer optimization problems. Ongoing research efforts include parallel programming efforts for mixed-integer optimization, including parallel nonconvex nonseparable mixed-integer outer approximation and parallel nonconvex branch-and-reduce methods. Application areas of interest include particulate processing, bio-processes, and large scale systems.
