From what you have described, I would think you have just as good a chance as anyone to be accepted. On paper (assuming you do well on the GRE) your GPA is your weakest point. However, you have 3.5 years of research experience, which will definitely work in your favor. Letters of recommendation are important, so make sure you have good ones! Really put time into the written portions of your application - they are what will help a committee decide whether they want to interview you or not. Numbers are important, but what you write in your application and what your recommenders say about you are probably more important. Finally, make sure you prepare for your interviews when the time comes! The interviews are your chance to make up for any shortcomings, and to show that your strengths and accomplishments are as great as they seem on paper. Good luck!
