We study the links between human health and human movement
Movement is a critical element of human contact and connectivity, which drive pathogen transmission. We work to measure human movement to understand pathogen transmission and access to health care, particularly in areas where a lack of understanding of human contact has limited progress in public health.
It’s impossible to vaccinate a population adequately without knowing how many people make up a population.
Populations change over years, seasons, and weeks. Sometimes, they change regularly or predictably, which can help inform vaccination efforts. Our work measures these changes and quantifies how predictable they are to help close gaps in vaccination coverage. Our work in this area is primarily in Niger and Namibia.
We use satellites to measure anthropogenic lights
There are lot of sources for official population size numbers and they’re never the same. This creates uncertainty when vaccination programs calculate how many to administer to a population to achieve ~92% coverage, to break local chains of measles transmission.
