Who we are

Here’s a bit of information about those of us involved in running the site.  Let us know if you want to join and help out!

Matt Greenall

greenall_medMatt has been working on HIV, human rights, and various other areas of health for nearly 15 years, and for half of that time has been independent, working for various clients (UN organisations, governments, NGOs), mainly in African countries.  He spends most of his time analysing and synthesising different sorts of data, helping organisations to plan and design their HIV/AIDS programmes, and reviewing and evaluating them.  He also gets to work with community groups, helping them conduct research and training them in programme development.  Matt’s main areas of expertise are programmes with “key populations” such as sex workers and men who have sex with men, and “community systems” for health.  You can find his tweets here and his personal blog here.

She also works with non governmental organisations on advocacy and the creation of plans and products that will influence policy.

Kate has a first degree in Social Psychology and a Masters in Human Rights. She has worked as a Creative, a Policy Manager, Communications Officer and Researcher in a diverse range of organisations.
