At 6'5", Aaron Dennis towers over the whiteboard beside him. Blue marker in hand, the 22-year-old hunches slightly to jot down suggestions being shouted by a group of people deep into a brainstorming session. Dressed mostly in nerdy T-shirts (one reads Science! with a test tube in place of the letter i), they're trying to come up with names for a tech tool they plan to build during a two-day hackathon at Tufts University’s data lab.
The group includes computer science PhD candidates, mathematicians, political operatives, and experts in so-called geographic information systems, or GIS. That’s the mapping technology that underlies many apps and software tools that run our lives, from Google Maps to logistics software.
It also comes in handy when you’re carving the American electorate into voting districts that favor your political party, a time-honored—and reviled—tradition known as gerrymandering.
