Communication, Teamwork and Leadership training for CyberInfrastructure Professionals. This project provides professional skills training curriculum for technically proficient CI Professionals, with the goal of developing CyberAmbassadors who are prepared to lead multidisciplinary, computationally-intensive research at their home institutions. CyberAmbassadors will also be prepared to help mentor the next generation of CI Professionals and CI Users, who will become a sustaining source of new CyberAmbassadors. Using current pedagogical approach a curriculum is provided that builds professional skills (communications, teamwork, leadership) within the context of large scale, multi-disciplinary computational research. The curriculum is provided on a free, open-source basis, with the longer-term goal of making the CyberAmbassadors training regularly available at academic and research institutions nationwide.
