Biography: 

Dr. Choi began at Tech in Fall 2006 as an Assistant Professor. Prior to joining Georgia Tech, he was a research assistant at Wright State University, conducting research on uncertainty quantification techniques for the analytical certification of complex engineered systems. As an Engineer Officer in the South Korea Army, he led the team that constructs military facilities and also trained soldiers to carry out military tasks. Dr. Choi’s research combines state-of-the-art numerical techniques in statistical methods and structural analysis methods with innovative uncertainty quantification techniques. His current research focus is on the development of robust simulation and decision-support tools to assist the management of complex engineered systems involving multi-scale products and distributed real-time systems. He has received awards for his research and scholarship, including a competitive Fellowship award from MIT for research in computational mechanics. He is the principal author of a graduate-level textbook on the topics of probabilistic mechanics and reliability-based design optimization (Reliability-based Structural Design, Springer, 2006). He is a member of AIAA and a member of Tau Beta Pi, the engineering honor society. He is a reviewer of the AIAA Journal and the Journal of Computational Physics on the topics of uncertainty quantification and stochastic analysis.
