Chair – United Kingdom


Nyambe’s overarching interests over the years have been in rights and practice associated with access to health, especially in relation to populations at the periphery of services due to their marginalised and vulnerable situations. Having begun as a volunteer in the area of prevention strategies and access to sexual health services, he is now a lead in Asset Based Community Development within the sector.
