Dr Maria Val Martin

I am an atmospheric scientist with a research focus on understanding the composition of the atmosphere and its interactions with the biosphere and climate. My work explores how human activities, land use changes, and natural processes—such as wildfires—affect these systems and contribute to global environmental challenges.

My work integrates advanced numerical models, including atmospheric chemical transport, land, and Earth system models, with field data and satellite observations. With these tools, I address pressing questions about atmosphere-biosphere-climate feedbacks, air pollution, and the use of land-based carbon dioxide removal strategies—such as afforestation/reforestation, wetland restoration and enhanced weathering—to mitigate climate change.

Passionate about public engagement, I actively work with schools and communities to raise awareness of environmental issues. I lead the UK’s first Air Quality Garden at the Sheffield Botanical Gardens, a project designed to educate the public on urban air quality and its impacts on human and vegetation health. I also organize outreach events to inspire action on climate change and air pollution.
