Cyberinfrastructure Facilitators play a crucial role in helping researchers maximize the value they get from the computing-intensive/data-intensive aspects of their research. And, their ranks have been growing steadily, as more institutions employ more CI Facilitators. The skills that they need to be successful include not only technical topics but especially professional/interpersonal/soft skills, because CI Facilitation depends on teaching, cultivating relationships and leadership. To address this need, the Virtual Residency Program has been teaching key CI Facilitation skills since 2015, to pre-service and in-service CI Facilitators, at introductory, intermediate and advanced levels. In this presentation, we'll look at what the Virtual Residency has been doing, how, and why.
