Diversity Statement for IAS-USA Activities

Diversity adds to the richness of scientific discourse. The IAS–USA is passionate in promoting diversity and inclusivity in all aspects of our organization, including our programs and activities. We vigilantly ensure that they represent diversity in areas including (but not limited to) sex/gender identity, sexual orientation, race/ethnicity, and national origin. For CROI, we are particularly focused on strong international representation among the invited speakers and conveners, including representation from resource-rich and -limited settings, and on establishing opportunities for new investigators and trainees.
