Daniel Erchick, PhD, MPH, is an epidemiologist and faculty member in the Department of International Health at the Johns Hopkins Bloomberg School of Public Health. His research focuses on interventions to improve neonatal and infant survival and growth in low-resource settings. His experience includes conduct of community-based randomized controlled trials (RCT) and observational studies. Currently, he works on an RCT to evaluate the impact of a balanced protein energy supplement for mothers during pregnancy on incidence of adverse pregnancy outcomes in rural Nepal. He is also involved in two modeling studies, which, respectively, aim to understand the detailed patterns of neonatal and infant mortality by age and sex and generate global estimates of the phenotypes of vulnerable newborns (i.e., combinations of preterm, small-for-gestational age, and low birth weight).
