He has built organizations from inception alongside founding teams, designing governance structures, leading strategic planning, and developing junior talent into capable leaders. His doctoral research at Northwestern University examined the impact of climate change on sustainable cities, a systems-level lens that continues to inform how he coaches leaders and teams today.
