We're an impact-oriented team of systems thinkers and doers, working to collaboratively build emerging fields.

Spark accelerates emerging climate mitigation and adaptation approaches, focusing on new ideas and research that are currently under-addressed and under-resourced, but potentially high-impact. We work with scientists, policymakers, and peer organizations to support the growth of fields with potential for limiting warming, managing Earth systems risk, and helping repair the climate.

He received his Ph.D. from the Department of Forestry at North Carolina State University.

Charles Brooke

Program Lead, Enteric Methane

Charles leads enteric methane field roadmapping and program development at Spark, building off of his existing science, policy, and practice expertise in the field. Prior to joining Spark, Charles served as the lead scientist for short lived climate pollutants within the executive office of the California Department of Food and Agriculture where he created and managed the first state program to support enteric methane research. He has also worked as an affiliate researcher at the University of California, Davis, focused on the evaluation of feed additives for enteric methane mitigation, rumen microbiome responses and the discovery of novel microbial compounds

Katrine Gorham, Ph.D.

Program Manager, Atmospheric Methane Research

At Spark, Katrine is leading the atmospheric methane research funding program and roadmapping. Prior to Spark, Katrine managed science programs and operations, most recently for the NSF Office of Polar Programs Arctic Research Support and Logistics contract, as well as for the NSF National Ecological Observatory Network and the UC Davis Air Quality Research Center. Katrine studied atmospheric chemistry at UC Irvine (PhD ’09).

Danielle (Danie) Potocek, Ph.D.

Natural Systems Scientist

Danie is a biogeochemist focused on scientific road-mapping and field building of Spark’s Natural System Response program. She received her PhD in Earth Sciences from the University of Southern California and conducted postdoctoral work at Caltech. Her past research includes trace metal and cofactor cycling in natural systems, as well as the role these trace nutrients played in Earth’s critical biological innovations. She has extensive experience in field sampling and method develop. In addition to her academic training, she also has 6+ years of experience in environmental and climate policy consulting at the local, state, and Federal levels. In her spare time she enjoys gardening, running, and exploring the Chesapeake Bay with her family.

Ryan Price

US Policy Manager

Ryan leads policy initiatives and engagement for Spark. He previously worked for the New York City Department of Environmental Protection, the Environmental Defense Fund, the Office of Legislative Affairs at the White House and helped to manage the carbon dioxide removal policy initiative at the Linden Trust for Conservation. He has extensive experience in federal climate policy design and advocacy.

Sam Abernethy, Ph.D.

Methane Removal Scientist

Sam is a climate scientist focused on scientific roadmapping and program-building at Spark. He received his Ph.D. in 2024 from Stanford University. Sam has authored several of the key early papers in atmospheric methane removal and point source methane oxidation, and his past research includes Earth system modeling, determining how to compare greenhouse gases, and evaluating different methane removal technologies.

Paige Brocidiacono (Brown)

Project Manager, Atmospheric Methane Research

Paige supports work across methane removal from solutions research and roadmapping to community building. Before Spark, as a Thiel Fellow, Paige co-founded 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. She has a B.S. in Materials Science from Stanford University.

Jasmine Woods

Operations Associate

Jasmine comes to Spark with a wealth of experience in operations at nonprofit organizations. She was the operations manager of health programs at a Congreso de Latinos Unidos in Philadelphia and, most recently, helped lead recruiting and employee development at a tech consulting firm specializing in building volunteer management systems for nonprofits. At Spark, she works with our Chief of Staff to ensure Spark’s operations, finances, and team and culture scale smoothly.


Remi Bouteille

Co-founder, Advisor

Remi is passionate to discover and scale a wide array of solutions to ensure a stable climate. Remi is also the co-founder and Strategic Advisor for the Climate Pathfinders Foundation, and instigated the formation of Carbon Gap and The Climate Map.
