Tyler B. Evans, MD, MS, MPH, AAHIVS, DTM&H, FIDSA currently serves as the medical director for Alameda County (CA) (including Oakland) Health Care for the Homeless Program, one of the largest populations of people experiencing homelessness in California. During the COVID-19 response, Dr. Evans held a number of positions, including the chief executive and medical officer (CEO/CMO) for Curative Medical Associates, Inc, which worked with Curative, Inc to provide the mass administration of COVID-19 vaccines across the nation administering >2 million doses in 10 states with a focus on health equity. Prior to this, he was the deputy public health officer and chief of the COVID-19 vaccination branch at Marin County Health and Human Services Agency. Previously, he served as the CMO for the NYC Office of Emergency Management medical section focusing on the COVID-19 response. He has held  other CMO posts overseeing community health centers focusing on homelessness, substance abuse and migrant health, as well as leading infectious disease divisions in a number of organizations across the US – including the AIDS HealthCare Foundation (AHF).

With training in tropical medicine/infectious disease, internal medicine, preventive medicine/public health, and epidemiology, he has worked extensively with vulnerable populations both in the US and abroad. In addition to a number of international missions (mostly in sub-Saharan Africa, South Asia and the Middle East) with Medecins Sans Frontieres (MSF) (Doctors without Borders), Partners in Health (PIH) and other global organizations, he has also worked domestically serving Native Americans with the Indian Health Service (IHS), as well as at a large federally qualified health center (FQHC) in NYC, where he established one of the first refugee/asylee integrated primary care/mental health programs. He is one of the founders of the NYC Refugee and Asylee Health Coalition (NYCRAHC).

In terms of populations, he is most drawn to working with special populations, including migrants (namely refugees, asylees and victims of human trafficking), the LGBTQ (with a special focus on transgender populations), the homeless, and Native Americans. He is currently focusing on the mental health needs of women affected by gender-based violence (including conflict-related gang rapes) in the Democratic Republic of Congo (DRC). In terms of fields of medicine, most of his experience is in HIV/AIDS, hepatitis C, TB, neglected tropical diseases (NTDs), travel medicine, as well as general primary care and community health. Academically, his research interests are in HIV, hepatitis C, tropical and travel medicine, transgender health, and health inequalities. He is strongly committed to health equity and social justice. He holds three faculty appointments at USC and University of California, San Francisco (UCSF). He is a fellow at the Infectious Diseases Society of America (IDSA) and serves on the board of directors for the HIV Medical Association (HIVMA). He splits his time between Santa Cruz, CA and New York, NY.
