We are excited to announce that [Professor Hans Rosling](http://en.wikipedia.org/wiki/Hans_Rosling), Director of the [Gapminder Foundation](http://www.gapminder.org/) and Professor of International Health at [Karolinska Institutet](http://ki.se/ki/jsp/polopoly.jsp?d=130&l=en), has joined the Open Knowledge Foundation’s [Advisory Board](http://okfn.org/advisory_board/)!
The Gapminder project is an excellent example of how public data can be built upon to create rich and compelling new applications. Hans is a strong proponent of allowing public data to be accessed and re-used. Futhermore his experience in emerging visualisation technologies will be extremely useful in directing the OKF’s projects and activities in the area of [open visualisation](http://okfn.org/wiki/OpenVisualisation/Workshop).
For more on Gapminder you can see their collection of [videos](http://www.gapminder.org/videos/) incorporating interactive visualisations of all kinds of interesting data – including the famous [Debunking Myths about the Third World](http://www.gapminder.org/videos/ted-talks/hans-rosling-ted-2006-debunking-myths-about-the-third-world/) and [The Seeming Impossible is Possible](http://www.gapminder.org/videos/ted-talks/hans-rosling-ted-talk-2007-seemingly-impossible-is-possible/) talks from [TED](http://www.ted.com/), and presentations on everything from [energy](http://www.gapminder.org/videos/gapcasts/gapcast-10-energy/) to [public services](http://www.gapminder.org/videos/gapcasts/gapcast-9-public-services/), [urbanisation](http://www.gapminder.org/videos/gapcasts/gapcast-2-urbanization/) to [globalisation](http://www.gapminder.org/videos/gapcasts/gapcast-4-globalization/).
Welcome aboard Hans!
