Ever ask yourself, “What am I doing with my life?” No? Well, a little existential crisis is in order then. Because while you and the rest of Team teen America were busy dressing like Gaga, dancing to the Bieber and playing Angry Birds, high school senior Angela Zhang was killing cancer. Yes, this 17-year old medical prodigy from Cupertino was just awarded the Siemens Foundation grand prize — a $100,000 payday — for her work “Design of Image-guided, Photo-thermal Controlled Drug Releasing Multifunctional Nanosystem for the Treatment of Cancer Stem Cells.” It’s certainly a mouthful, but this nanotech is what one fellow researcher’s calling the “Swiss Army knife of cancer treatment,” as her gold and iron-oxide nanoparticle does double duty delivering the drug salinomycin to a tumor site, in addition to aiding MRI and photoacoustic imaging. If that’s not impressive enough, this real-life lady Doogie Howser’s also won Intel’s ISEF grand award in both 2010 and 2011 for other health science-related work. Sure, Angela might inadvertently fall into the overachiever category, but girlfriend definitely deserves to win that Prom Queen crown.
