Dr Li is mainly fascinated in developing and applying (1) probabilistic and statistical methods to engineering risk/reliability problems, and (2) optimization methods to inverse engineering problems in the field of structural engineering. Engineering risk assessment consists of uncertainty quantification and propagation through physics-based (e.g., nonlinear finite element) and/or data-based modeling. This serves to assist decision-making in the process of probability-based design, retrofit, and maintenance in the face of uncertainty. He is also extensively involved with inverse engineering problems (e.g., structural design optimization, nonlinear FE model updating using field-recorded and experimental data). Specifically, his research interests includes:
- Mechanics-based nonlinear FE simulation
- Stochastic modeling of natural hazard loads
- Probabilistic mechanics and dynamics
- Risk and reliability analysis
- Soil-structure interaction
- Performance-based engineering and innovative engineering solutions
- Nonlinear system identification and model updating
- Statistical learning for health monitoring
- High throughput computing
