Erika DeBenedictis, a 2009 Davidson Fellow, won the Intel Science Talent Search last night for her project developing a software navigation system to help improve spacecraft travel through the solar system. Her research looked at gravity and how the planets move to help create "easy transit routes," (per the Intel press release) which will "ultimately help spacecraft move faster and with less fuel." You can read about her Intel project here, and about her Davidson Fellowship here.
(I also interviewed her for a Wall Street Journal article last fall on why it wasn't a bad thing for kids to be very busy).
She's a very impressive young lady and I'm sure we'll be hearing a lot more from her in coming years. In the meantime, now that she's won another $100,000 in scholarships from Intel, I'm not sure there is a college that's expensive enough to cover all her winnings!
