Update: The former “developmental” UW Behavioral Research Center on HIV (BIRCH) has been funded for an additional 5 years as a *FULL* AIDS Research Center as of September 18, 2026! We are now the Behavioral Innovation Research Center on HIV and we have a new HIV & Aging Core. Many of our services will remain the same and we will offer pilot awards in HIV and mental health. Please stay tuned in the coming months as we ramp up a re-imagined BIRCH! -Susan, Lydia, and the BIRCH Team
