Margaret Denise Portman (27 May 1974 – 6 February 2019) was a British medical doctor who specialised in sexual health.
She advocated for access and usage of pre-exposure prophylaxis medication (PrEP) to reduce incidence of HIV/AIDS in the United Kingdom.
[4] While there, she worked on the PROUD study, which demonstrated that a daily dose of the drug Emtricitabine/tenofovir (brand name Truvada) was effective at preventing HIV infection in gay and bisexual men.
[1] She joined Mortimer Market Centre, part of Central and North West London Foundation Trust (CNWL) in September 2015.
[5] After HIV activist Greg Owen launched the website IWantPrEPNow—a site where those in the United Kingdom could order generic PrEP, which was not available in-country—Portman became involved with the project.
