Isaiah Williams is a Master in Public Policy candidate at the Yale Jackson School of Global Affairs, focused on regenerative agriculture, environmental justice, and climate policy for sustainable development. As a licensed professional engineer with experience spanning infrastructure resilience and grassroots environmental action, he explores how public policy can scale nature-based solutions and strengthen food system resilience in ways that center equity, empower communities, and restore ecosystems.

Prior to joining the Jackson School, Isaiah served as a Peace Corps volunteer in Veraguas, Panama, where he collaborated with smallholder families to design climate-resilient agroecological systems in the face of a historic drought. He also supported the formation of women-led family gardens groups in his community and authored an intersectional training proposal to recognize and integrate Afro-Indigenous contributions to sustainable agriculture within Peace Corps training programs. Before his international service, Isaiah worked as an engineering consultant for six years, where he led diverse teams to deliver infrastructure solutions while managing junior staff and guiding technical design for multi-million-dollar projects across the U.S.

After Yale, Isaiah aims to lead teams crafting policies that scale localized regenerative agriculture successes into global climate frameworks — sequestering carbon while partnering with frontline communities and advancing just, resilient food systems.

Isaiah earned a bachelor’s degree in environmental engineering from the University of Connecticut. He is fluent in Spanish and is learning Brazilian Portuguese.
