Susie Welty is the lead on special initiatives for the UCSF Pandemic Initiative for Equity and Inclusion (UPIEA). She has 15 years of public health experience primarily in HIV/AIDS in east Africa. She works as a contact tracer, case investigator, team lead, and trainer for the San Francisco Department of Public Health pandemic response. She also supports new initiatives for UPIEA. Susie grew up in a Quechua Indian village in Ecuador, and witnessed firsthand people turned away from health care because of their ethnicity.
