I've been in a lab for 18 months. I have some findings, but really can't develop a story around it. I'm working on the function of a novel gene product - can't seem to find any "important" function yet. I have another project in the lab that I am working on with someone else. I have no publications. I have presented my work, however. I was thinking on waiting for another six months and see how it goes before talking to my advisor about whether to call it quits or not. Has anyone else faced a similar situation?
