Florian Bach
Postdoctoral Scholar, Infectious Diseases
BioI'm a molecular infection biologist by training, but shifted my focus from pathogens to hosts for my graduate research. During my PhD with Phil Spence in Edinburgh I studied both falciparum and vivax malaria using controlled human (re)infection models, collaborating closely with the groups of Simon Draper and Angela Minassian in Oxford. As a hybrid bioinformatician and experimentalist, I love systems immunology for answering complex questions about human health. For my postdoc, I study in how the human immune response to malaria evolves in infants as they become reinfected and age. I'm also interested in how such early-life immunological events, malaria and beyond, may affect vaccine responses and immune development later in life. I address this question by making use of a longitudinal study cohort of infants receiving monthly chemoprevention in Eastern Uganda, together with our collaborators at UC San Francisco and IDRC Uganda.

Catherine Blish
George E. and Lucy Becker Professor in Medicine
Current Research and Scholarly InterestsThe major goal of our research is to gain insight into the prevention and control of HIV and other viral pathogens by studying the interplay between the virus and the host immune response. We investigate the role of various arms of the immune response, but with a particular focus on NK cells. We hope to gain additional insights into control of infectious diseases by studying how pregnancy modulates immune responses.

studies interactions between phages and both their human and bacterial hosts with the goal of developing innovative strategies to improve human health. -
Hector Fabio Bonilla
Clinical Professor, Medicine - Infectious Diseases
BioAs a young physician at Louisiana State University, Dr. Bonilla focused on the Clinical Management of HIV/AIDS and HCV, two neglected and stigmatized diseases for which effective therapies were in their infancy. While learning the clinical aspects of the two diseases, Dr. Bonilla saw a need to create and organize a support community to promote understanding and management of the conditions. Subsequently, he went to Summa Health System in Akron, Ohio, and he continued his work where he specialized in HIV/HCV as well as in Infectious Diseases Clinical Practice. In addition to teaching medical residents and students, Dr. Bonilla participated in numerous clinical trials and developed clinical research projects. Furthermore, he led the Infection Renal Transplant Program, HIV and HCV clinics, and he participated in several cooperative studies with Case Western Reserve University. Dr. Bonilla’s interest in academia led him to the University Of Pittsburgh Medical Center where he was an Assistant Professor, Clinician, and Medical Educator in the Department of Medicine in the Division of Infectious Diseases. Due to his interest in cytokines and immunological responses, Dr. Bonilla became a researcher at ImmunoScience Inc., a biotechnology company in California that works to develop a therapeutic HIV vaccine. Dr. Bonilla’s experience of treating HIV/HCV combined with his interest in inflammatory response is the driving force behind his desire to understand ME/CFS. Dr. Bonilla is a strong patient advocate, and he believes in integrated care—care in which physicians communicate and coordinate efforts to deliver the best medical outcome for patients. His ME/CFS patients are his inspiration, and he is committed to continuing research to seek answers to their health challenges.

Brian Dawes
Fellow in Medicine - Med/Infectious Diseases
Current Research and Scholarly InterestsMy current research is focused on better understanding the causes of acute febrile illness in Grenada in collaboration with the Windward Research and Education Foundation (WINDREF). We are conducting an acute febrile illness cohort and performing diagnostics for common arboviral infections including dengue, Zika, and chikungunya viruses. We will use this data to develop better estimates for the incidence of arboviral infections on the island and identify epidemiologic risk factors which could be the target of preventative interventions. This study is also assessing a novel diagnostic system for antigen detections in collaboration with Dr. Ali Yanik at UCSC. We will be testing these samples for hantavirus infections or antibodies to determine if hantaviral infections are clinically important causes of disease in Grenada. In addition, we are performing a pilot ecologic survey of rodents and bats and will attempt to identify circulating hantaviruses in these species.

Vanessa El Kamari
Instructor, Medicine - Infectious Diseases
BioVanessa El Kamari, MD, is a physician-scientist in the Division of Infectious Diseases and Geographic Medicine at Stanford University and a member of the David Relman Laboratory. Her research investigates how host–microbe interactions in the small intestine regulate mucosal immunity, barrier integrity, and systemic inflammation in autoimmune and inflammatory diseases.
Her current studies use non-invasive sampling of the small intestine in conditions such as celiac disease, multiple sclerosis, and environmental enteropathy. She applies an integrative, multi-omic approach—combining microbiology, immunology, molecular biology, and computational biology—to define spatial immune–microbial networks along the human gut.
Before joining Stanford, Dr. El Kamari’s research focused on inflammation and immune activation in chronic HIV infection, where she identified gut barrier dysfunction as a key driver of systemic inflammation and cardiometabolic complications. She also led intervention studies targeting immune activation and endothelial dysfunction in HIV, work that laid the foundation for her current efforts to apply similar mechanistic approaches to autoimmune and inflammatory disorders. -
