Early life exposure to and colonization with microbes has a profound influence on the education of the immune system and susceptibility to viral and bacterial infections later in life. My research is focused on the influence of the upper respiratory microbiome on the development of recurrent respiratory infections, including acute otitis media (AOM), the leading cause of antibiotic prescriptions and healthcare consultations among children. Importantly, some children develop recurrent infections that are thought to be linked to dysbiosis of the nasopharyngeal microbiome. My overarching goals are to identify alterations in the upper respiratory microbiome associated with AOM and to elucidate host factors and exposures that predispose some children to the development of recurrent AOM episodes.

Children's Health & Discovery Initiative:
The prenatal period, infancy, childhood, and adolescence, represent critical time periods of human development that include more developmental milestones than any other period of the lifespan. Conditions during these developmental windows – including biological, social, economic, health, and environmental factors – have a profound impact on lifelong health. The Children’s Health and Discovery Initiative (CHDI) was founded on the hypothesis that interventions early in life will improve population health across the lifespan. To this end, the overarching goal of the CHDI is to create a robust coalition of multidisciplinary investigators and a pipeline of infrastructure, data, and research projects focused on developing innovative approaches to identifying and modulating early life factors that impact lifelong health and well-being.
