Dr. Diego Ponce de Leon Barido is founder of threestone analytics (threestone.io), where he works on developing information and communication solutions and ubiquitous data products for reducing waste in cities of Latin America. Recently, threestone designed and implemented the first two randomized pilots for micro-level flexible demand and behavioral energy efficiency in Latin America, with 360 participants in Managua, Nicaragua. Diego has extensive experience in sustainability science, and has designed, implemented and scaled various information technology solutions for urban sustainability. He has worked on the design of open-source software for fostering low-carbon (low-impact) energy systems and economic development in Nicaragua, on grassroots sustainability efforts in Chiapas (Mexico) developing regional microcredit schemes and river survey studies, designing buffered rainwater and pumped-solar small water distribution systems in rural Uganda and Honduras, has used GIS and hydrological models to study the long-term sustainability of the Linthipe Basin (Malawi), and investigated linkages between hydrological variability, energy use, and agriculture in Punjab and Telangana (India).

Dr. Ponce de Leon Barido holds a PhD in Energy and Resources with a Designated Emphasis in Development Engineering (UC Berkeley), an M.S in Energy and Resources (UC Berkeley), a B.S.C.E in Civil Engineering (University of Minnesota), and a B.A in Economics (Macalester College). He is a Link Foundation, National Geographic Energy Challenge, and CONACYT-UCMEXUS fellow. His work has been supported by the USAID Development Impact Lab, the Interamerican Development Bank, and the National Geographic Society. He is currently at UC Berkeley’s CITRIS Foundry, scaling the work of threestone.io in Latin America.
