Summer research in the US
I'm looking in to the possibility to do research in the US during the next summer. In the spring I will finish my basic science courses so I don't have any clinical experience (guess that rules out clinical research?).
However I don't know if it useful to do research during such a limited time (2-3 months) or if it is better to do it at my home institution were I can continue with it during the semesters?
Secondly, what is the procedure when looking for research positions in the US? Do you just contact the group leader or is there some special kind of procedure? Also, is it difficult to be accepted? I'm interested in cardiology and have a little (basic) research experience in the field but no publications or presentations...
