Looking for a PhD position

Hello,

I am a student, conducting the final year of my Master's Programme.
>From here I would like to go on to do a PhD in a field related to
molecular biology.
I'm having a hard time looking for available positions, however.

I know about http://www.findaphd.com/ which has a nice database of
programmes available in the UK. What about other European countries?

Are there other such websites? How else would you look for available
PhD opportunities in the field of molecular biology?

I will be grateful for any information,

Michal Karzynski
