The 'Yellow Pages' of CDR

5+ years working on carbon removal - Drafted CDR procurement legislation to build durable demand for credits - Led work on carbon removal at COP, helping put CDR on the global agenda - Supported industry orgs including Carbon Gap and RMI to advance the field - Now building a novel CDR pathway at Kairos Carbon, turning organic waste into permanent carbon removal. Get in touch if you're interested in what we're doing at Kairos!

Retired from 25+ years in biomass pyrolysis / biochar and 40+ years in the industrial & petrochemical and engineering arenas.

🌍 Applying science and technology to impactful initiatives. I’m a data scientist with 3+ years of experience at the intersection of physical science, climate resilience, and big data. I’m passionate about translating complex climate data into actionable insights—whether maintaining early warning systems, analyzing global climate trends, or communicating with diverse collaborators and audiences. With a background rooted in environmental research and a commitment to humanitarian values, I thrive on turning research into practical solutions. Are you also interested in building a more sustainable, equitable, data-informed future? Let's connect!

Working on CarbonBank project of Direct Air Carbon Capture with Long duration Energy Storage to stabilize Renewable Grid. Passionate about futuristic Innovation and how Technology is built on sound Science. Also working on Cooling for Data centers & Oxy-fuel combustion Carbon Capture for Net-zero world.

St Andrews alumnus in Geochemistry MSc, specialising in biogeochemistry and chemical weathering. Experienced in delivering and communicating lab- and field-based research projects, including one presented at Goldschmidt’s 2025. Proven experience in using lab equipment, including ICPMS, IC, XRF, spectrophotometer. Strong analytical skills in data analysis, modelling tools and programming languages like R, Python, PHREEQC and MS Office. Excellent leadership, organisational and collaborative skills. Excited to develop carbon removal technologies to fight climate change. Proactive, self-motivated.

I believe every climate solution is a link in a long chain, and I have found my link in biochar. It started with a curiosity for soil, carbon, and how we can do things better. Biochar gave me a way in. It connected science with people, land with policy, and carbon with care. Since then, I have worked with startups, researchers, and farmers to explore how this small black material can make a big difference. Now I am part of the global effort to make carbon removal real, measurable, and lasting. I do not have all the answers, but I am adding my piece to the puzzle, one project, one idea, one collaboration at a time.
