Professor, Georgia Tech, School of Computational Science and Engineering


Complex systems are hard to simulate and even more difficult to optimize. In this talk, I will showcase how surrogate models accelerate the evaluation of properties of solutions to partial differential equations. I will present a precise definition of the computational benefit of surrogate models and example surrogate models. We will then show how surrogate models can be combined to solve a challenging multiscale problem in optics. We will show that, through a synergistic combination of data-driven methods and direct numerical simulations, surrogate-based models present a data-efficient and physics-enhanced approach to simulating and optimizing complex systems. This approach has the benefit of being interpretable. I will also share ways forward and opportunities for synergistical collaborations.
