<p>I guess my perspective from meeting students accepted this year is I’ve seen many more well-rounded students than specialists. Now, I’m not saying at all to tone town the specialty (I completely agree with Data’s comments on passion), it’s just that having a broad base can be a good sign to Stanford admissions because this fits with their ideas of academic flexibility and intellectual vitality. They love people who like exploring varying intellectual paths and how these may intersect with an area of focus, at least from what I’ve seen and heard. The scientific research of the OP is an excellent demonstration of passion, and her integration with community service reflects very nicely with admissions. I’m saying that in my experience I’ve met many students that seem more well-rounded than specialized, however you’ll find a mix of both on campus at any selective university.</p>
