About

I’m a climate scientist by training, and over the past decade I’ve worked on a wide range of topics related to climate, land use, and sustainability – in research, at the science-policy interface and while creating climate services. I bring together a solid scientific record and analytical skills with experience supporting stakeholders across the public, private, and third sectors, from local to international levels. I also have a track record in securing funding and coordinating multi-partner projects. Fluent in French, English, and German, and proficient in Spanish, I thrive in international environments and am passionate about translating scientific information into impact. I enjoy both high-level policy or scientific discussions and technical deep dives, and I’m especially motivated by working across disciplines, institutions, and cultures, and helping others do the same. I’m particularly interested in applied research and advancing climate action through strategic science-policy engagement and delivering climate services.
