I joined the Department of European & International Studies (EIS) at King’s College in September 2025. Before, I lectured in Environmental and Latin American, Caribbean, and Latinx Studies at Brandeis University, MA, USA. I completed my PhD in International Development at the London School of Economics and Political Science.

My research spans international, environmental, and development studies, grounded in sociology. I examine the relationship between environmental politics, climate finance, and uneven development, particularly how international green strategies affect agrarian conflict and traditional populations.

My book manuscript, Where Money Grows on Trees. European Carbon Politics in the Brazilian Amazon is currently under revision. It critically examines G7 environmental aid to the Brazilian Amazon, as well as the construction and local disputes surrounding institutional and technological structures for green economies, including carbon markets. My second book, The Herbarium of Rosa Luxemburg. Radical Ecology and the Global Plantation, published by OR Books in April 2026, combines the first transcription and translation of Luxemburg’s original annotated herbarium with a discussion of her critical ecology. I hold a Master's degree in Sociology from the New School for Social Research and a Diploma in Sociology from the Technical University of Dresden.

Between 2018 and 2023, I was based in Belém, Pará, Brazil, where I also worked as an international cooperation advisor for the Belém city government.
