I am doing a combo of basic science and clinical. I am analyzing patient samples, doing mutation analysis for a disease called Morquio syndrome (MPS IVA). I do lots of "bench research" but then I also have to do genotype/phenotype correlation which involves lots of patient information. IN fact it looks as if I will be able to write up a nice case report on a new mutation that we found in one patient!
I have several friends who had no prior experience who are doing basic science research (biochem, pharm, micro, molecular genetics etc...) and I also have some who are doing clinical research (chart reviews, case reports, etc...) You may want to look to see if your medschool has some kind of sponsored fellowship program (mine does) which you apply for. If not just find some topic you are interested in and meet with the PI. Yes they may aske for a resume, but don't sweat it if you have no prior experience. They will work with you.
