David co-founded Spark, and drives science initiatives. He was previously a senior fellow at RMI, and co-founder and advisor to The Climate Map, which became the RMI Carbon Removal Initiative. David has also led product teams at Dropbox, invested in climatetech at Khosla Ventures, and led climate-focused teams at McKinsey & Company. David studied Applied Physics at Stanford (PhD '06) and Physics at Harvey Mudd.

Erika co-founded Spark, and leads the org. Her background is in leading product engineering groups at high-growth software companies, with an impact orientation. Previously, she started and co-led U.S. Digital Response's work to provide local election offices across the country the products and technical expertise they needed to run a smooth election, led the Payments Experience engineering group at Stripe, served as the Director of Engineering at OpenAI, and was the Director of Product Engineering at Planet Labs after being an early engineer there. Erika studied computer science, electrical engineering, and mechanical engineering at MIT. She lives in San Francisco with her young family.

Eric Davidson is Professor of the Appalachian Laboratory of the University of Maryland Center for Environmental Science. His research includes terrestrial nutrient cycling, greenhouse gas emissions from soils, global biogeochemical cycles, and sustainable agriculture. Davidson is Past President and Fellow of the American Geophysical Union, Fellow of the American Association for the Advancement of Science, Web of Science Highly Cited Researcher, and Senior Editor for AGU Advances. Davidson received his Ph.D. from the Department of Forestry at North Carolina State University. His book Science for a Green New Deal; Connecting Climate, Economics, and Social Justice was published in 2022.

Paige is doing her best to create a better world for her future children. She grew up surrounded by nature in Maine, inspiring her to pursue climate action. After receiving the Thiel fellowship, she dropped out of Stanford to found WindBorne, which uses the constellations of the team's balloons to access hard-to-reach atmospheric data and improve the weather forecast to better adapt to climate change. In early 2022, she felt called to do more to address climate change and left WindBorne to return to finish her undergrad in Materials Science and join Spark to help catalyze the methane removal field.

Daphne leads Spark’s policy engagement on methane removal. Prior to joining Spark, she was the founding CEO of the NGO Methane Action. Before focusing on methane, Wysham was a fellow at Center for Sustainable Economy, and the Washington, DC-based Institute for Policy Studies and at Amsterdam's Transnational Institute, where she developed a global campaign to successfully challenge international financial institutions and export credit agencies to reorient their energy lending away from fossil fuels.  Wysham co-founded and for eight years co-hosted the syndicated show "Earthbeat Radio."  Aired on over 60 public radio stations across the U.S. and Canada, it shared groundbreaking news and information on the climate crisis and educated audiences about environmental and climate justice. A graduate of Princeton University, she lives in Port Townsend, Washington.

Laura is a dynamic generalist and is excited to put her skills to work towards repairing the climate. Previously, she worked at Nike for 10+ years, first in sustainability, where she identified and accelerated the adoption of technologies to lower the environmental footprint of materials. She then helped build an internal incubator to test and build new businesses that expand beyond Nike’s core business. Laura studied English at Stanford University.
