I've spent 2+ years in undergrad research on a narrow topic in biology and I'm applying for PhD programs in the fall. I have relatively broad interests so I would like to explore some different topics in cell/molecular biology before choosing an adviser and will apply to umbrella programs/ programs with first year lab rotations.
However, I am worried about how to express this, if it would come off as unfocused or not having a good research 'fit' for a particular department.
Can anyone offer advice on how to express this desire in my SOP without hurting my chances for admission?
