Brett McMann presently serves as The Institute’s project manager for all Louisiana Watershed Initiative activities, all activities related to CPRA coastal master plans, and all compound flood prediction projects within The Institute. He has consistently been tasked with managing The Institute's largest projects, which account for roughly 25-30% of Institute revenue since 2022. An adept team leader and consensus builder, Brett manages up and down organizational charts of highly capable hydrodynamic modelers, statisticians, mathematicians, and civil engineers to deliver projects that often push the boundaries of coastal and flood science.
