Research interests + projects

Dr. Cao’s research focuses on the design and implementation of large-scale local and global optimization algorithms to tackle problems that arise in diverse decision-making paradigms such as machine learning, stochastic optimization, and optimal control. His algorithms combine mathematical techniques and emerging high-performance computing hardware to achieve computational scalability. His goal is also to make these developments accessible to academic and industrial users by implementing algorithms on easy-to-use and extensible software libraries.

Furthermore, Dr. Cao has applied the algorithms and tools to address engineering and scientific questions that arise in diverse application domains, including deep-learning-based control, global optimal AI, optimal power system planning, AI-based design of biomass-based carbon removal processes, image classification for contaminant detection, optimal design of zero energy buildings, and modelling of battery systems.
