Hi all I have had two "official" research experiences/projects in the last year. The first one was in plasma physics and now I am doing one in the math department in operations research/statistics. Both projects were interesting and resulted in presentations at symposia/conferences. The first one was not published, but the data may someday be used by a graduate student for his graduate research. the second one I presented at two math conferences, but there is only a remote possibility of publishing that one and I would have to work really hard to find something uniquely original and that has never been done before in it. My question is, does it look bad to graduate school applications that I have only done conference presentations, but none of these resulted in published papers? Does that make them think I will be a bad researcher?
