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. -
Stacey Bent
Jagdeep & Roshni Singh Professor in the School of Eng, Professor of Energy Science and Eng, Senior Fellow at Precourt & Prof, by courtesy, of Electrical Eng, Materials Sci Eng & Chemistry
BioThe research in the Bent laboratory is focused on understanding and controlling surface and interfacial chemistry and applying this knowledge to a range of problems in semiconductor processing, micro- and nano-electronics, nanotechnology, and sustainable and renewable energy. Much of the research aims to develop a molecular-level understanding in these systems, and hence the group uses of a variety of molecular probes. Systems currently under study in the group include functionalization of semiconductor surfaces, mechanisms and control of atomic layer deposition, molecular layer deposition, nanoscale materials for light absorption, interface engineering in photovoltaics, catalyst and electrocatalyst deposition.

Paul Bergeron
Lecturer
BioDr. Paul Bergeron is a lecturer in the physics department, focusing on teaching the 40 series and engaging in curriculum reform. His background is in dark matter phenomenology, working on supersymmetric extensions to the Standard Model, detection of dark matter at neutrino telescopes, and the programmatic tools used by the community to make predictions. While doing particle physics research, his time was split with teaching, first as an LA at UCSC during his undergrad and then during his PhD at the University of Utah as a TA, Head TA, adjunct lecturer at a community college, and instructor for a continuing education course in astronomy that he developed. His time at the University of Utah also included Physics Education Research (PER) into the efficacy of Content Rich group problems as part of a curriculum redesign effort in the department there. Following his PhD, he did a post doc with the interdisciplinary education research group 3 Dimensional Learning for Undergraduate Science at Michigan State University. While there, he worked with faculty in the STEM Teaching and Learning Fellowship as they worked to align their teaching with how scientists think and do science, while doing research into the corresponding gateway course transformation effort and into student engagement with the Scientific Practice of using and constructing (scientific) models. After his post doc, he worked for two years as a professor at Pasadena Community College teaching introductory physics and astronomy lectures and laboratories. Originally from San Jose, he is excited to finally be back in the Bay Area and to be a part of the Stanford community!

Carolyn Bertozzi
Baker Family Director of Sarafan ChEM-H, Anne T. and Robert M. Bass Professor in the School of Humanities and Sciences and Professor, by courtesy, of Chemical and Systems Biology
BioCarolyn Bertozzi is the Baker Family Director of Sarafan ChEM-H, Anne T. and Robert M. Bass Professor in the School of Humanities and Sciences and Professor, by courtesy, of Chemical and Systems Biology and of Radiology at Stanford University, and an Investigator of the Howard Hughes Medical Institute. She completed her undergraduate degree in Chemistry from Harvard University in 1988 and her Ph.D. in Chemistry from UC Berkeley in 1993. After completing postdoctoral work at UCSF in the field of cellular immunology, she joined the UC Berkeley faculty in 1996. In June 2015, she joined the faculty at Stanford University and became the co-director and Institute Scholar at Sarafan ChEM-H.
Prof. Bertozzi's research focuses on fundamental studies of disease-associated glycobiology and the development of new therapeutic modalities that target these pathways. Her inventions include bioorthogonal chemistries for in vivo imaging and bioconjugation, work for which she received the 2022 Nobel Prize in Chemistry. As well, her lab has developed next generation antibody-drug conjugates, lysosome-targeting chimeras (LYTACs), antibody-enzyme conjugates and antibody-lectin chimeras. Several of these new therapeutic modalities have been translated into clinical candidates for treatment of cancer and autoimmune diseases.
In addition to the Nobel Prize, Prof. Bertozzi has been recognized with many honors and awards for both her research and teaching accomplishments. For example, she is an elected member of the National Academy of Sciences, the National Academy of Medicine, the National Inventors Academy and the National Academy of Engineering, the American Academy of Arts and Sciences, the German Academy of Sciences Leopoldina, and she is a Foreign Fellow of the Royal Society. In addition, Prof. Bertozzi received the Priestley Medal of the American Chemical Society, the Welch Award, the Wolf Prize in Chemistry, the Heineken Prize, Lemelson-MIT award for inventors, and a MacArthur "Genius Award".
