David is researching strategies to assess exposure to microbes in the environment. He is using molecular techniques to characterize fecal contamination in the household environment in urban Maputo, Mozambique. This research will be used to evaluate a large-scale sanitation intervention and its effects on child health. He is also working on a geostatistical tool to predict microbial contamination at the watershed level, and is developing a statistical framework for estimating the contribution of different fecal pollution sources in a set of environmental samples.
