About
I have been living with HIV since 2018. When I received my diagnosis, I was in my forties, in the middle of a life that wasn't simple — I had experience with chemsex and several years of intensive self-searching behind me. The diagnosis came as a relief: I finally understood where my chronic fatigue was coming from.
I started treatment immediately. I have been undetectable ever since — which means I cannot transmit the virus to others. This principle, known as U=U (Undetectable = Untransmittable), is one of the cornerstones of my work: I strive to ensure that every person living with HIV I work with understands U=U and reaches undetectability as quickly as possible.
I became one of the first Buddy Polska volunteers to publicly disclose their HIV status. At the time, I was still working at Johnson & Johnson, where I spent 14 years in roles including strategic marketing and patient engagement across Central and Eastern Europe.
Today I coordinate projects, advise institutions, and represent the perspective of people living with HIV at the European level. I hold a PhD in Neurobiology (Otto von Guericke University, Magdeburg, 2008), a certified HIV/AIDS counsellor qualification, and I am currently completing a Master's degree in Psychology. In 2023, I was awarded the Red Ribbon by the Polish Ministry of Health. I am affiliated with the Polish Scientific AIDS Society and the European AIDS Clinical Society.
Projects

Poland's first nationwide peer support programme for gay and bisexual men recently diagnosed with HIV.

Foundation for Social Education · Certified HIV/AIDS Counsellor

As part of broader collaboration with FES, I also contribute to projects including: HIV/STI testing in prison settings, HIV training for foster care professionals, and HIV training for those working with people experiencing homelessness.
European AIDS Treatment Group · Member, Chair of DMAG
EATG is Europe's largest patient-led HIV organisation, active since 1992. I serve as Chair of the Development and Membership Advisory Group (DMAG) — an advisory body responsible for evaluating membership applications, monitoring member engagement, and overseeing EATG's compliance with its constitution and internal regulations. DMAG advises the Board of Directors and the General Assembly, and notifies the Board in cases of constitutional breach. I am also a member of the Combination Prevention Committee (since 2024) and a graduate of the STEP-UP Training Academy (2021).
