I’m a freelance writer with three years’ experience specialising in the climate sector. As a result, I have a deep knowledge of the science, policy, and financial landscape surrounding the energy transition. I’ve worked with over 20 startups, nonprofits, and consultancies, delivering authoritative content and thought leadership aimed at general audiences, industry leaders, and policymakers. With a background in journalism (reporting for Reuters among others), I’m confident interviewing stakeholders at all levels. I write with accuracy and rigour, and can perform in-depth research. My strength is finding the key messages that will resonate with an audience, and communicating them in a clear and impactful way, without losing nuance.
