Assistant Professor of Biology and, by courtesy, of Structural Biology
Current Research and Scholarly InterestsResearch in our lab is aimed at defining the structural correlates of broad and potent antibody-mediated neutralization of viruses. We combine biophysical and structural methods (e.g., cryo-EM), protein engineering, and in vivo approaches to understand how enveloped viruses infect host cells and elicit antigen-specific immune responses. We are particularly interested in the co-evolution of HIV-1 and broadly-neutralizing IgG antibodies (bNAbs), which may hold the key to the development of an effective HIV-1 vaccine. In addition, we are investigating antibody responses to SARS-CoV-2 and related zoonotic coronaviruses (CoV), with the related goal of developing broadly-protective immunotherapies and vaccines against variants of concern and emerging CoV threats.

Associate Professor, Biology
Current Research and Scholarly InterestsPlants make new leaves and stems from clusters of undifferentiated cells located at the tips of branches. These cell clusters are called apical meristems. We study transcription factors that control growth and development of apical meristems. Our studies include plants growing in environments rich in water and nutrients as well as in poor environments. The deeper knowledge of plant development gained from these studies will ultimately help increase food security in a changing environment.

Stefan Oliver Bassler
Postdoctoral Scholar, Biology
BioStefan is a Bridging Excellence Postdoctoral Fellow in the Petrov lab at Stanford University and in the Aulehla & Steinmetz labs at EMBL (2025-now). He is fascinated by how evolution can be used to probe the genomic plasticity of biological systems. During his PhD with Nassos Typas at EMBL supported by the Joachim Herz Add-on Fellowship, he mapped the Genomic landscape of resistance evolution by performing high-throughput resistance evolution of the genome-wide KO library in E. coli. He discovered that evolvability genes constrain resistance evolution through gene-gene and gene-gene-drug interactions. In his postdoctoral work, he will Assess the inter-kingdom conservation of lifespan variants evolved in yeast.

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 savanna ecology in the Cerrado.
Driven by pursuing 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 ecology 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 Chico Mendes Institute for Biodiversity Conservation (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.
