Welcome
The ACTG welcomes investigators from outside our funded Clinical Research Sites to engage with the network. There are many ways to get involved based on your interests and goals and participation in site activities is not required. Opportunities include applying to join scientific committees, submitting new research concepts for potential protocol development, and requesting access to our robust sample and data repositories.
Early-career investigators, fellows, postdoctoral researchers, and new faculty are strongly encouraged to get involved and to learn how the ACTG can help support your research goals.
Scientific Committees
The research conducted by the network is generated through five major Transformative Science Groups (TSGs): Antiretroviral Therapy, HIV Cure, Tuberculosis, Comorbidities, and Viral Hepatitis. These groups are complemented by cross cutting groups focused on Behavioral Science, Women’s Health, Neurology, and Implementation Science. Committee members rotate at regular intervals. Membership applications are solicited annually, and self nominations are welcome and encouraged. These committees review concepts submitted to the network for consideration for development into network clinical trials. The TSG’s also review requests to use samples and data.
