Madeleine Price Ball is a Biophysics graduate student in George Church's lab at Harvard University. Don't be impressed - she hasn't published anything yet, although she thinks she's got a good idea this time. She has a personal webpage if you're really feeling curious.
Her husband, Chris Ball, has his own blog. He works at One Laptop Per Child and likes to talk about computer things. He's British and has a cute accent!
Madeleine likes to edit Wikipedia under her real name. She used to use "Madprime" but felt it was silly since there wasn't any secret about it.
In case you're curious about distant past - Madeleine attended Caltech in '97-'98 & '99-'02, graduating with a Biology major. They still made her do some physics though. She was a Mole. Before this she attended La Jolla High School, as did her three awesome younger siblings.
