Charlotte V. Hobbs, MD
Senior Faculty Development Leader
Dr. Hobbs is a Professor of Pediatric Infectious Disease and Microbiology at the University of Mississippi Medical Center (UMMC), Children's of Mississippi. She completed her fellowship in Pediatric Infectious Disease at New York University/Langone Medical Center and Bellevue Hospital in New York, NY. She was then awarded a position in NIAID's Transition Program in Clinical Research as an Assistant Clinical Investigator in the Laboratory for Malaria Immunology and Vaccinology. During her 5 years at the NIH, she established a truly translational research program, having investigated the immunological and pharmacological effects of HIV drugs in animal and in vitro models of malaria infection as well as through clinical studies in Lilongwe, Malawi and Rakai District, Uganda. Currently, she continues work in this vein with collaborators at NIH. In parallel to this work, she is conducting epidemiologic studies in Mississippi, performing surveillance in children for soil-transmitted helminths infections, in collaboration with the CDC. With the COVID-19 pandemic, she has initiated pediatric safety studies in schools and seroprevalence studies which have had significant impact on school re-opening guidelines. Dr. Hobbs is PI of the Overcoming COVID-19 CDC/Harvard study at UMMC, contributing to multiple recent high level publications which aim to characterize SARS CoV2 in children. In addition and within this context, she is also specifically leading the COVID-19 disease characterization in infants study as well as the multi-system inflammatory syndrome in children (MIS-C) exposures study. Overall, her work aims to benefit children from resource limited settings, as parasitic infections such as soil-transmitted helminths tend to occur more frequently in these settings, in parallel to her work in pediatric COVID-19, which she believes remains a neglected disease (under-research and explored, with great biological and social impact) within our pediatric populations. Dr. Hobbs believes that her experience in various academic centers, from NYU/Bellevue to NIH to now UMMC, in addition to her experience working both internationally and domestically in global health as a physician scientist, lends itself well to collaboration with ISPCTN.
