Is 1&1/2 research going to be enough by the time I apply?

<p>Hey all,
So I'm working for a famous professor since the beginning of this summer(I am a junior now).. By the time I apply I will have 1 and 1/2 years of research including two summers. I spent my sophomore year working in another guys lab but figured that I didn't really want to do it, hence the change. Will be it be enough for top 10 schools? I am in chemical engineering by the way.</p>

<p>Thanks!</p>
