In a post in the Bill & Melinda Gates Foundation’s “Impatient Optimists” blog, Gary Darmstadt, head of the Family Health Division of the foundation, Wendy Prosser, a research analyst with the Family Health division, and Wolfgang Munar, senior program officer in the Family Health Division, examine how knowledge networks “can be leveraged to bring upstream technologies to downstream adoption in order to achieve impact at scale,” writing, “Knowledge networks link people across disciplines and sectors to keep members abreast of new ideas, data, evidence and practical applications.” They continue, “These networks are instrumental in sharing knowledge, generating ideas, and bringing innovation like [exclusive breastfeeding and life-saving vaccines] to spread to all those who need them” (10/3).
