Welcome to my home page! My name is Prattana (Sandy) Punnakitikashem. I am a Ph.D. candidate in an Industrial and Manufacturing Systems Engineering Department at the University of Texas at Arlington (UTA). I received a B.S. degree in Chemical Engineering from Chulalongkorn University, Bangkok, Thailand, in 2001. I also received a Masters in Industrial Engineering from UTA in 2003. Before joining UTA, I had internships at the Petroleum Authority of Thailand Exploration & Production, Public Company Limited, the Unocal Corporation, and the Sherwin Williams Company. Currently, I work as a research assistant for my advisor, Dr. Jay Rosenberger, in the area of applied optimization in healthcare services. My recent work is developing the nurse-patient assignment decision support model, an algorithm, and the information technology prototype for nurse assignment. Click here for more information about our project. I am a member of Center on Stochastic Modeling Optimization and Statistics (COSMOS).

My research interests are in operations research, stochastic optimization, optimization in healthcare, and large-scale optimization.
