Haochen Li

Assistant Professor


His lab, Water Infrastructure Laboratory (Ψ Lab), leverages and integrates physical modeling (e.g., particle image velocimetry, PIV), first-principles simulations (e.g., computational fluid dynamics, CFD), and artificial intelligence (AI) techniques (e.g., machine learning, ML) to address challenging issues in the urban water cycle and sustainable development. The missions of the Ψ Lab are to advance multiphysics and multiphase flow prediction in natural and built water infrastructures and to enable robust and efficient next-generation water infrastructure planning, design, optimization, and management.
