Dear Colleague, We have the pleasure of inviting you to participate in a new and ground-breaking study by the Program on Humanitarian Policy and Conflict Research (HPCR) at Harvard University. This research project focuses on the role of professional networks in the dissemination of innovation and best practices in the humanitarian sector. As a first step of this project, we would like to seek your support in mapping current professional networks in the humanitarian sector. If you would like to collaborate with us on this project, please click below to answer a few short questions for study eligibility purposes. Once you complete the first questionnaire, you will receive in the following days a link to an anonymous research survey, which will take approximately 15 minutes to complete. We encourage you to forward this message to colleagues and members of your professional networks in the humanitarian sector, who would be interested in participating in this exciting initiative. The aggregate results of the survey and its analysis will be shared with all participants. We very much look forward to and appreciate your participation. Thank you!
