Dr. Laura Hammitt is an Associate Professor at the Johns Hopkins Bloomberg School of Public Health. Her research focus is the epidemiology and prevention of pediatric infectious diseases, with a particular interest in Streptococcus pneumoniae, Haemophilus influenzae, and the ecology of the human microbiome as it relates to treatment and prevention of disease.
