Network Methods

I've also had a long-standing interest in drawing on network theory to evaluate and improve methods - particularly of data collection. This has lead to my involvement in a number of primary data collection projects (in Malawi, South Africa and New York City), and evaluation of secondary network data (in Colorado Springs).

Some of the questions this has entailed include estimating the returns from particular network-based sampling strategies, and evaluating the corroboration between multiple reports of the same behaviors. I'm in the process of a new collaboration with Sara Yeatman and Stéphane Helleringer on developing "Third Party Reports" a strategy for improving population-level estimates of sensitive behaviors by asking respondents not to estimate their own behaviors, but those of their friends.
