thanks aj.. i hav something to start on now..

Hi, I have come across a PhD. opportunity in spain which asks just preferences of choice from 4 different deparments in Biological research to work in but does not say anything about peculiar topic on which one would be working on. So i have no idea what to write in 'research interest/ what do you intend to do in your PhD.' column since i dont want to write something that might slim my chances in another group but dont know how to write that could appeal to all groups which are
Bioinformatics and GenomicsGene Regulation Cell and Developmental Biology Differentiation and Cancer Genes and Disease Any suggestions pls.
