Daniel Zavala-Araiza

International Scientist


Areas of expertise:
Environmental impacts of energy systems, Climate Change, Sustainability, Social impacts of science and technology

Daniel Zavala-Araiza, Ph.D. is an international scientist in the Texas office of Environmental Defense Fund. His current work focuses on methane emissions from the global oil and gas system with an emphasis on measurement and characterization of emissions. He provides scientific guidance and coordination for the CCAC Oil and Gas Methane Science Studies.


Dr. Zavala-Araiza obtained a B.S. in chemical engineering from Universidad Iberoamericana, Mexico City, and a Ph.D. from the University of Texas at Austin, where he carried out research on environmental implications of shale gas production.

He has additional graduate studies around the social implications of science and technology and has worked in Environmental Justice projects in Mexico. He has taught courses on sustainability and environmental science.


Ph.D. – University of Texas at Austin

B.S. – Universidad Iberoamericana (Chemical Engineering)
