On November 16th, COSMOS Ph.D. student Bancha Ariyajunya successfully defended his dissertation, entitled “Adaptive Dynamic Programming for High-Dimensional, Multicollinear State Spaces.” His dissertation committee included COSMOS faculty Dr. Victoria Chen, Dr. Jay Rosenberger, and Dr. Li Zeng. His dissertation addressed the problem of correlated variables in a dynamic programming state space. His methodology was originally motivated by airport deicing activities and was tested on an ozone pollution control optimization. In airport deicing, the state of the system considers the environmental impact of deicing, and the environmental variables are highly correlated. In ozone pollution, the state of the system considers ozone concentrations in the air, and these are highly correlated over time and space. Bancha’s research was supported by grants from the National Science Foundation and the Dallas-Fort Worth International Airport. His current research interest is in the area of statistical modeling and data mining.
