Experiences & Accomplishments
Daniel Erchick, PhD, MPH, is an epidemiologist and community-based trialist in the Department of International Health at the Johns Hopkins Bloomberg School of Public Health. His research focuses on interventions to improve maternal health and neonatal and infant survival and growth in low-resource settings. Currently, he works on an randomized trial to evaluate the impact of balanced energy protein supplementation during pregnancy and lactation on incidence of adverse birth outcomes and infant growth in rural Nepal. He leads a longitudinal cohort study to characterize the vaginal microbiota and assess associations with participant characteristics among pregnant and non-pregnant women in rural Bangladesh. He is also involved in a study to describe the prevalence of and risk factors for small vulnerable newborns (i.e., combinations of preterm, small-for-gestational age, and low birth weight).
