Ruth Belay, MD
Clinical Assistant Professor, Urology
BioDr. Belay is a fellowship-trained urologic oncologist with the Stanford Health Care Urologic Cancer Program. She is also a clinical instructor in the Department of Urology at Stanford University School of Medicine.
Dr. Belay specializes in diagnosing and treating disorders of the urinary tract, including kidney cancer, enlarged prostate, ureteral stones, and blood in the urine. She also treats all types of genitourinary cancers. She is skilled in the use of multiple imaging and treatment modalities, including cystoscopy, endourology, laparoscopy, laser therapy and surgery, ultrasound, urodynamic testing, ureteroscopy, and robotic surgery. Dr. Belay works closely with her patients to provide a comprehensive evaluation and care plan.
Her research interests include pain control during robot-assisted prostatectomy (prostate removal) and determining the best types of guidewires for bypassing stones in the ureter. She has also studied the effects of caffeine on postmenopausal women with overactive bladder symptoms
Dr. Belay is involved with the Stanford Medicine Center for Improvement, the goal of which is to inspire and accelerate the delivery of consistent, excellent care across Stanford Medicine. She is also passionate about sharing her knowledge of urology with medical students, having taught and mentored several residents and post-doctoral fellows.
Dr. Belay’s research has appeared in several peer-reviewed journals, including Urology Practice, Journal of Endourology, and Journal of Women’s Health. She has presented her work both nationally and internationally at meetings and conferences of professional organizations including the American Urological Association (AUA); Society of Urodynamics, Female Pelvic Medicine & Urogenital Reconstruction; and World Congress of Endourology.
Dr. Belay is a member of the AUA and Society of Urologic Oncology. -

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. -
Luca Bellodi
Postdoctoral Scholar, Political Science
BioLuca Bellodi is a research fellow at the Hoover Institution and a postdoctoral scholar in the Department of Political Science at Stanford University. His current research focuses on American political institutions, specifically the interaction between politics, bureaucracy, and populism, and its consequences for the quality of government.
In Bellodi’s primary line of research, he studies politicians’ incentives to control the behavior of bureaucratic agencies, lawmakers’ reliance on bureaucratic expertise, and the role of bureaucracy in shaping the political agenda. He introduces innovative measurement strategies that combine natural language processing techniques and machine learning to address novel questions in the study of oversight, rulemaking, and the use of information in the policymaking process.
In a related line of research, Bellodi investigates why politicians adopt populist behaviors and examines the consequences of populism for government performance and the quality of bureaucracy.
Luca Bellodi holds a PhD in political science from University College London. Before joining Stanford, he was a postdoctoral research fellow at Bocconi University in Milan.
