Rodrigo Bello Carvalho
Ph.D. Student in Biology, admitted Autumn 2023
BioI 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 Biology Teaching (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. -

Yvonne Boesch
Postdoctoral Scholar, Biology
BioYvonne received her Bachelor’s and Master’s degrees from ETH Zurich and obtained her PhD in Biology, specializing in fungal denitrification, from the Swedish University of Agricultural Sciences (SLU) in Uppsala under the guidance of Prof. Sara Hallin.
In January 2025, she joined the Peay Lab as a postdoctoral scholar, supported by the Swedish Wallenberg postdoctoral scholarship program.
Yvonne is fascinated by the intricate interactions among microbes and their relationships with higher organisms, such as plants. Her research focuses on exploring how these complex relationships impact plant health, forest productivity, and resilience in the face of changing environments. -
Carol Boggs
Bing Director in Human Biology, Emerita
Current Research and Scholarly InterestsI am interested in how environmental variation affects life history traits, population structure and dynamics, and species interactions in ecological and evolutionary time, using Lepidoptera.
