E'jaaz A. Mason
Lecturer, Earth Systems Program
BioE’jaaz A. Mason is a Lecturer in Earth Systems at Stanford University teaching courses about community-engaged multimedia environmental storytelling. He is also the Co-Founder of Lede New Orleans, a nonprofit fostering community engagement and young adult media production training. A filmmaker, educator, and community engagement specialist, Mason was a member of the 2023-2024 John S. Knight Journalism Fellowship at Stanford. From 2015 to 2020, he taught film and digital media in New Orleans public high schools, founding an award-winning film program at New Orleans Charter Math & Science High School. Mason has received numerous awards for his work in youth education. He was a cinematographer for the 2022 HBO/Time Studios documentary Katrina Babies and is the Story and Impact Producer for the 2025 documentary The River. He is also directing two documentary films: Black Suit: Sewing [Her]story, which highlights the importance of Black women in New Orleans’ Black Masking Indian culture and an untitled film about environmental and societal challenges facing residents of the Bayview Hunter's Point neighborhood in San Francisco.

Diana Moanga
Lecturer, Earth Systems Program
BioDiana A. Moanga, PhD, is a Lecturer in the Earth Systems Program at Stanford University’s Doerr School of Sustainability. She teaches courses in geographic information science (GIS), remote sensing, spatial analysis, and geospatial data science, including Fundamentals of Geographic Information Science, Advanced Concepts in Geographic Information Science, and Remote Sensing of Land, Biology and Global Change, and mentors undergraduate and graduate students through independent research.
Her teaching emphasizes applied, problem-based learning that connects geospatial methods to real-world environmental and societal questions. She designs GIS coursework around place-based analyses, spatial problem solving, cartographic communication, and independent student projects, with the goal of helping students move beyond learning software to understanding how spatial thinking can be used to investigate complex problems. In 2025, she received the Stanford Doerr School of Sustainability’s Excellence in Teaching Award in recognition of her contributions to teaching, curriculum innovation, and student learning. Her approach to GIS education was also featured by Esri in the 2026 article, Making GIS Click: Lessons from a Stanford Classroom.
Dr. Moanga’s research spans coastal resilience, land system science, conservation, and coupled human–environment systems, with particular expertise in GIS, remote sensing, and spatial analysis. Her work examines how environmental and anthropogenic pressures reshape landscapes and coastal systems, including land-use and land-cover change, wildfire, flooding and coastal hazards, ecosystem services, and nature-based approaches to resilience. Across this work, she is particularly interested in developing spatial methods and decision-support frameworks that translate complex environmental data into information that can support conservation, planning, and climate resilience.
She earned her PhD in Environmental Science, Policy, and Management from the University of California, Berkeley in 2020. Her doctoral research used geospatial methods to examine land-use and land-cover change across California, including the effects of conservation management on coastal lands, agricultural transitions in the Central Valley, and wildfire activity under changing climate conditions. She earned her MS in Marine Affairs and Policy and BA in Marine Affairs from the University of Miami, where her research included harmful algal blooms, coastal zone management, and coral conservation.
Before joining the Earth Systems faculty in 2023, Dr. Moanga was a postdoctoral researcher in Stanford’s Department of Earth System Science and at Florida International University’s Sea Level Solutions Center. -
Dena K Montague
Environmental Justice Lecturer, Earth Systems Program
BioDena Montague is an Environmental Justice Lecturer at Stanford University. She is also the Founder and Executive Director of ÉnergieRich, an early-stage start-up establishing community based local manufacturing of solar energy systems in Ghana. ÉnergieRich develops collaborative research partnerships between Ghanaian engineers and engineers in the African Diaspora to implement innovative energy solutions that center community voices. Her research focuses on energy justice through decentralized production; impacts of Global North clean energy transition on climate/environmental justice in the Global South. Prior to her position at Stanford, she was a Postdoctoral Scholar at Duke University and Lecturer at The Bren School of Environmental Science and Management at UC Santa Barbara.
