I'm currently a junior at an Ivy, planning to apply next year. I've been doing biochem research since my freshman year in a well known lab at my school. So far, I've gone to conferences and given poster presentations, but still no publication! I was mainly wondering if this would be looked down upon, since I am likely applying to many top tier, research heavy schools. A lot of people around me brag about their 20+ publications in Cell and Nature. But to me, it just seems like getting a publication is largely out of the student's control. Another thing. During high school and up to the summer before I started college, I worked in a biochemistry lab at UChicago. However, earlier this year I got my name on a publication from my old lab. It was work I did during high school, but the publication came after I started college. Given that it takes time to accumulate data and write a paper, is this still relevant to medical schools?
