"Epidreamiology" is the name I use to describe the guesswork that is common in the planning and design of AIDS programmes. But the blog also talks about other stuff.
None of it is peer-reviewed, so please feel free to comment.
In real life, I'm a freelancer, primarily involved in designing/advising/evaluating HIV and AIDS programmes in low income countries. I work for lots of different organisations, but the views on this blog are all mine.
