Hi,
I want to pursue Phd in bio informatics. Can anyone tell me if there are any positions in Europe

I'd expect so! Best way is to familiarise yourself with the major figures in the field you're interested in by way of journals. Check out their websites and/or contact them dirctly. Some PhD places are advertised in the back pages of science mags too.

Try out Imperial College, they really want PhD Bioinformatic students
