David A. Relman
Thomas C. and Joan M. Merigan Professor and Professor of Microbiology and Immunology
Current Research and Scholarly InterestsMy investigative program focuses on human-microbe interactions and human microbial ecology, and primarily concerns the ecology of human indigenous microbial communities; a secondary interest concerns the classification of humans with systemic infectious diseases, based on features of genome-wide gene transcript abundance patterns and pther aspects of the host response.
Cybele A. Renault, MD, DTM&H, FIDSA
Clinical Associate Professor, Medicine - Infectious Diseases
BioDr. Renault has devoted her career to caring for vulnerable patient populations, both domestically and overseas. She completed her medical school and residency training at the University of Chicago, caring for underserved patients on Chicago's South Side, followed by a Chief Resident year at John H. Stroger, Jr. Hospital of Cook County, the public hospital serving the uninsured in Chicago. She began her career in global health as an Infectious Diseases fellow at Stanford, validating low-cost HIV diagnostics in Burkina Faso, and providing clinical service and teaching in India and Zimbabwe as a fellow, and later in Thailand, Uganda, Rwanda and Kenya as one of our Infectious Diseases faculty. Her clinical work is focused on caring for our Veteran population, working to empower Veterans to engage in their care, often in the setting of significant mental illness.
Dr. Renault is most passionate about medical education and program development to combat global antimicrobial resistance through antimicrobial stewardship, to create opportunities for the Internal Medicine residents centering on caring for vulnerable patient populations, and to develop impactful and sustainable programs in collaboration with our low- and middle-income partners for our Center for Innovation in Global Health. She served as Associate Program Director for the Internal Medicine Residency Program for 4 years prior to transitioning to her current role as Program Lead for Global Health, for which she leads the Global Health Track for the Internal Medicine residency program and develops global health initiatives for the Department of Medicine. She co-founded and has been director of the Stanford 2-week intensive global health course since its inception in 2012, she has structured trainee and faculty rotations based on evolving needs of our partner sites in Uganda, Rwanda and Zimbabwe, she is the faculty lead for the ID/antimicrobial stewardship partnership between Stanford and Moi Teaching and Referral Hospital in Eldoret, Kenya, and she is leading Stanford's multi-disciplinary efforts to support our newest partner in Negele Arsi, Ethiopia.
Dr. Renault strives to augment Stanford's contributions and support for underserved patient populations in the United States. She established resident rotations in Shiprock, New Mexico and Chinle, Arizona through the Indian Health Service, and she is Faculty Advisor for the Internal Medicine Health Equity, Advocacy and Research concentration in the residency program. She also aspires to improve resources for women physicians. In 2016, Dr. Renault established the GME Women in Medicine Leadership Council, with the intention of creating community and encouraging conversations about professional and personal life decisions as women in the field of medicine. She is passionate about mentoring through sharing personal experiences, creating an environment that encourages reflection, and building skills to address challenges unique to women in medicine.
In 2022, in recognition of her passion for medical education and her success in program development, Dr. Renault was asked to join the leadership at Palo Alto Veterans Health Care System as Deputy Associate Chief of Staff for Education. In this role, she works with rotation directors to optimize their respective rotations to offer robust educational opportunities for trainees across specialties who are rotating at the Palo Alto VA.
Izabela Mauricio Rezende
Postdoctoral Scholar, Infectious Diseases
BioI have a B.S. in Biology, M.Sc. in Immunology and Infectious diseases, Ph.D. in Microbiology. I am currently a Postdoctoral Researcher at the Stanford University School of Medicine, working with Dr. Jason Andrews at the new Stanford Pandemic Preparedness Hub, a fellowship I was awarded at the end of 2022. As part of a pandemic preparedness, We are tytrying to understand the potential viruses at risk of pandemic spread. Using disease modeling, epidemiological, and phylogenetic analysis, we study the genomic evolution and transmission dynamics of H5N1 avian influenza A after 2020.
I am in my third postdoctoral year at Stanford and completed the first two years with Dr. Desiree LaBeaud. I have a Ph.D. in Microbiology, with an emphasis in Virology, and a Master’s in Infectious Diseases. . My Ph.D. was conducted in Brazil, under the supervision of Dr. Betânia Drumond, and contemplated the virological and epidemiological aspects of yellow fever (YF) outbreak in Minas Gerais/BR in 2017-2018, combining laboratory, clinical, and data analysis (publications: DOI 10.1126/science.aat7115; DOI 10.1371/journal.pntd.0006538; DOI 10.1128/jcm.00254-22; DOI 10.3390/vaccines7040206; DOI 10.1186/s12985-019-1277-7). I came to Stanford University for my first postdoc with Dr. Desiree LaBeaud. For two years, I led an international NIH R01 project investigating the dynamics of the biggest YF outbreak in Brazil, including the description of a new syndrome, Late-relapsing hepatitis after yellow fever (DOI 10.3390/v12020222), and risk factors for severe YF. I was also involved in other projects regarding SARS-CoV-2 variants and disease severity in infants (DOI 10.3389/fmed.2022.896352), Rift Valley fever virus epidemiology in humans and animals in Kenya (DOI 10.1371/journal.pgph.0000505), and dengue virus evolution in Africa (ongoing Ph.D. candidate mentorship).
During the COVID-19 pandemic, we also supported the Brazilian Ministry of Health with the SARS-CoV-2 diagnosis in human samples and also in the investigation of the SARS-CoV-2 RNA in surfaces of density public areas of Belo Horizonte. Since Nov/2018 I had been an editor in the journal Docência do Ensino Superior (RDES / GIZ / UFMG) and in Jan/2020 I became Editor-in-Chief.
Arjun Rustagi, MD, PhD
Instructor, Medicine - Infectious Diseases
BioDr. Arjun Rustagi is an Instructor in Medicine. He is a graduate of the University of Washington Medical Scientist Training Program and Stanford's Internal Medicine Residency and Infectious Diseases Fellowship.
He is dedicated to understanding the early immune responses to infections, and the methods pathogens use to persist despite these responses, in order to inform new prevention and treatment strategies. He studies viral pathogenesis and immunity with Dr. Catherine Blish, under whose mentorship he set up the respiratory viral biosafety level 3 (BSL3) program at Stanford in early 2020 in order to study SARS-CoV-2, contributing to several projects in SARS-CoV-2 virology including a study of intact in vitro lung tissue infection. He also protocoled the first peripheral immune profiling study of severe COVID-19. His ongoing interest is in the full spectrum of in vitro respiratory viral models, particularly those that recapitulate lung epithelium and mucosal immunity.
