Postdoc Funding for an American looking to do a postdoc in europe (in Theoretical Computer Science) Hi I am doing a phd in theoretical computer science, and will be finishing this year and applying to postdocs for Fall 2016. I am an American, but for various reasons would like to study in Europe. Ideally the professors I am interested in would have postdoc funding available, but since that is often not the case, are there any grants/fellowships that cover postdoc salaries available for americans studying in europe? Are there other funding options I'm missing? Am I correct to assume that in europe like in America one gets postdoc funding from the professor (or from a grant), not from the department as a whole? As you can see, I know little about how funding works in Europe!

In case the answer to my question is country specific, the countries that I am most strongly considering so far are Germany and Switzerland. 

Thanks for your help!
UK is definitely of the 'professor has funding' variety of post-docs. However, there are also Fellowships. This is funding intended for a researcher doing their own research and there are programs specifically for Early Career Researchers. For example, there are Fellowships available through the EU Horizon 2020 program, see http://ec.europa.eu/programmes/horizon2020/ (note - extremely competitive) and through the various discipline funding councils, I think computer science would be https://www.epsrc.ac.uk/ and the fellowship info is at https://www.epsrc.ac.uk/skills/fellows/overview/.

You can also try organisations such as Fullbright.

A couple of other points - you should be clear about what you expect. I see lots of comments here about postdocs being training positions. This has not been my experience, I have had little supervision and no training. If you want training, you would be best off to join a project that involves several people, or seek a Fellowship with a training component. Also, make sure you are on the email / forum lists for academic communities that interest you, this seems to be where a lot of post-docs are advertised.
