Length and details of a personal statement in postdoc positions?
If they only ask for personal statement and CV then you need to find a way to squeeze in the personal statement basically everything. I would start by introducing what your studies were so far and what kind of results you got. Highlight the significance of your research and what are the next steps. Then write about collaborations you had and how you expanded your scientific network. Conclude by saying what your future plans in terms of career are. It is not an easy thing to write so I would start just writing down everything you can think of and then you start ordering things. With this kind of stuff the easiest way to tackle it is to just start writing. Ultimately it is a personal statement so you need to add some personal touch. Let people that knows you well read it and ask them their opinion even if they are not scientist. Good luck with your application!
