Earlier this month, Johns Hopkins sophomore George Chen flew to Seattle for an event hosted by the Saving Lives at Birth: A Grand Challenge for Development. He was there to show off an invention he’d developed (along with faculty adviser Soumyadipta Acharya and fellow students Noah Greenbaum and Justin Rubin) that uses cell phones to test for anemia. Though the event was hosted by deep-pocket global health organizations (USAID; the Gates Foundation), Chen didn’t really expect to come away with anything more than exposure. He definitely didn’t expect to walk away with a quarter million dollars in funding — but that’s exactly what happened. “When we thought about the big-name corporations and nonprofit groups we were competing against, we were amazed and surprised to find out that our team had won,” Chen told the Hopkins Gazette.
