Nittaya Phanuphak is the Executive Director of the Institute of HIV Research and Innovation (IHRI) in Bangkok, Thailand. She started her career in the HIV field in 2002 by leading a nationwide prevention of mother-to-child transmission operational study which resulted in Thai guidelines allowing the use of three-drug antiretroviral regimens for pregnant women in 2010.
Nittaya has a deep interest in Key Population-Led Health Services (KPLHS). KPLHS approaches empower lay providers who are members of KP communities to perform HIV/STI testing and dispense PrEP/PEP, antiretroviral treatment and STI treatment to their peers. She currently works towards the establishment of national accreditation and domestic financing systems for KP lay providers to ensure KPLHS sustainability. Nittaya also oversees the KP-led Princess PrEP program, HPTN 083 and the HIV self-testing and PrEP project for men who have sex with men and transgender women aged 15-19 years in Thailand.
Nittaya has served as the Asia Pacific representative in the IAS Governing Council since 2018.
