Grad School Help

<p>Hi</p>

<p>I am a senior in biomedical engineering at a school that is not considered a top tier engineering. I am currently applying to graduate school to pursue a PhD in biomedical engineering.
I have less than stellar GPA, 3.33 and my GRE scores are not so hot either 720 Quant and 440 Verbal. I have almost 3 years research experience working with gold nanoparticles and using them to develop a biological sensor. My junior year I was close to patenting and publishing my work but I was a bit too late because some guys in australia were a month early :(
Below are the schools I am applying to. Am I out of my league? Should I retake the GREs? Any other suggestions would be greatly appreciated. </p>

UIUC
NC State
Cornell
MIT
UC Irvine
Drexel
Northwestern
UMD-CP
NJIT
GW
