Bio


I am a field biologist deeply passionate about wildlife ecology and conservation. My academic and professional journey bridges research, fieldwork, and environmental stewardship across some of the world’s most biodiverse ecosystems.

My work focuses on understanding the functional role of megafauna (large-bodied vertebrates) in shaping tropical ecosystems through processes such as frugivory, herbivory, and seed dispersal. I am particularly interested in how savanna biodiversity, structure, and functioning respond to the loss of megafauna (defaunation), and how ecological insights can inform restoration and conservation strategies in a rapidly changing world.

I hold a Master’s degree in Biodiversity Conservation and Management from the University of Oxford (2021), and graduated with honors in Biological Sciences (B.Sc., 2017) and Education (B.Ed., 2018) from the University of Brasília (UnB). My ecological journey began at UnB’s Ecosystem Ecology Lab (2014–2018) under Prof. Mercedes Bustamante, where I first engaged with Cerrado ecology and savanna dynamics.

Driven by a commitment to applied conservation, I worked at the Brasília Zoological Garden Foundation (2018) and taught Science and Biology in Brasília’s private schools (2019), experiences that deepened my belief in connecting ecological science and conservation with communities.

At Oxford’s Ecosystems Lab (2020–2021), I studied defaunation and seed dispersal in the Cerrado, working under Dr. Imma Oliveras and Prof. Yadvinder Malhi. I later joined Brazil’s national environmental agency (ICMBio) as an Environmental Analyst and Park Ranger (2022–2023), where I was based in the Western Brazilian Amazon, engaging in biodiversity monitoring, sustainable management of natural resources, and frontline conservation enforcement of three Conservation Units within the Purus River Basin.


Currently, I am pursuing a PhD in Biology at Stanford University in the Dirzo Lab, where my research explores megafauna-ecosystem interactions across Brazilian and African savannas, with a focus on how defaunation reshapes ecosystems. I also collaborate with UNESP’s Bird Ecology Lab on frugivory, seed dispersal, and ecological restoration in the Atlantic Forest.

    Abstract

    In 2024, South America faced an unprecedented wildfire crisis, with Brazil among the hardest-hit countries. Home to globally significant biomes like the Amazon, Pantanal, Cerrado, and Atlantic Forest, Brazil's ecosystems are undergoing massive destruction. Despite the severity of the 2024 wildfires-surpassing even the internationally scrutinized 2020 wildfires-the current disaster remains underreported internationally. Here, we seek to raise global awareness and advocate for immediate, collaborative action to mitigate Brazil's escalating wildfire emergency. We examined the scope, ecological impact, and socioeconomic consequences of the 2024 fires in Brazil, highlighting record-breaking areas burned and widespread wildfire foci. These wildfires are devastating biodiversity, endangering public health, and intensifying environmental injustices across the country. Our analysis reveals a significant relationship between deforestation and wildfire incidence the following year. Smoke pollution reached hazardous levels, impacting urban populations and disproportionately affecting Indigenous communities. Key drivers of this crisis include unsustainable land-use practices, extreme climate conditions, and governance failures, with response efforts hindered by underfunded environmental agencies. This situation underscores the urgent need for stronger enforcement of environmental policies, rapid allocation of emergency resources, and the implementation of Brazil's Integrated Fire Management (IFM) programs across federal, state, and private lands. We call for sustained international support, directly targeted at Brazilian agencies, to bolster fire prevention, response, and ecosystem resilience. Protecting Brazil's biomes is a global priority, requiring consistent advocacy and action that transcends political shifts.
