Dr. Lim’s research interests are in Optimization, Operations Research Applications in Health Systems, Homeland Security, Power Systems, and Evacuation Planning and Management. He has a keen interest n developing optimization techniques (LP, MIP, NLP, and Stochastic Programming) to solving large scale decision making problems in such areas as medicine, biology, and transportation networks. His current research projects include Radiation Treatment Planning optimization, Operating Room Scheduling, Power Systems, and UAV scheduling and operations. His research projects are funded by SERRI-ORNL, Department of Homeland Security (DHS), Texas Department of Transportation (TxDOT), Qatar National Research Fund, the University of Houston, the University of Texas MD Anderson Cancer Center, and Varian Medical Systems, Inc.

Our research group conducts research on a variety of quality and reliability problems for complex systems. Our focus is on integrated quality and reliability models and analysis tools that provide fundamental insights for the successful development and commercialization of evolving technologies, such as Micro-Electro-Mechanical Systems (MEMS), biomedical implant devices, and nanotechnologies. Our research spans the domains of several fundamental research areas including quality and reliability engineering, probability and statistics, and optimization for advanced evolving technologies, homeland security, and healthcare systems. Our projects have been supported by Texas Higher Education Coordinating Board, Department of Homeland Security, UH Grant to Enhance and Advance Research (GEAR), Texas Department of Transportation (TxDOT), and National Science Foundation (NSF).
