CORE SUMMARY We aim to “engage and support the next generation of HIV structural biology researchers” by creating effective and diverse training opportunities. Our Developmental Core will accomplish this by implementing a series of training and development programs that will include four Components: 1) a Collaborative Development Awards Program designed to support talented young independent researchers who will benefit from and contribute to CHEETAH Center research projects and capabilities, 2) a summer, journal club-style Seminar Series that will expose Center trainees to the current HIV-1 literature and help hone their scientific presentation skills, 3) a Visiting Scholar Program for Center trainees that will include online training in the theoretical underpinnings and practical aspects of different biophysical and structural methods, followed by a 1-2 month “hands on” experience in which trainees will visit a Center lab or other training site to apply one of these methods to a problem of interest, and 4) Other Training Activities that will include virtual visual communication workshops for Center trainees that will provide them with practical guidance on creating outreach videos, animations, figures, and posters/presentations.
