Neera Singh in 2011, NETS now has more than 30<br />

undergraduates <strong>and</strong> will be capped at 40 incoming<br />

students annually.<br />

Kearns devoted much <strong>of</strong> last summer to producing six<br />

hours <strong>of</strong> content. He perfected explanations <strong>of</strong> complex<br />

concepts, yet stayed <strong>of</strong>f camera to use <strong>the</strong> screen to<br />

present information-rich concepts visually. He hopes to<br />

tap Coursera’s vast reach for his research, an approach<br />

that builds upon experiments conducted with Penn<br />

students. Influenced by <strong>the</strong> 2008 Democratic primary<br />

between Hillary Clinton <strong>and</strong> Barack Obama, he<br />

explored <strong>the</strong> link between network structure <strong>and</strong> how<br />

groups reach unanimity. His research, published in<br />

PNAS, demonstrated that a small but well-connected<br />

minority can systematically control <strong>the</strong> outcome <strong>of</strong><br />

decision-making against <strong>the</strong> will <strong>of</strong> <strong>the</strong> majority.<br />

“Those experiments injected energy <strong>and</strong> new material<br />

into <strong>the</strong> classroom, <strong>and</strong> generated published scientific<br />

articles that illustrated concepts for subsequent<br />

students,” Kearns says. He currently is developing<br />

<strong>the</strong> Warren Center, a new graduate program <strong>and</strong><br />

research initiative in network science funded by Robin<br />

<strong>and</strong> Frederick Warren, a Penn <strong>Engineering</strong> alumnus<br />

<strong>and</strong> Overseer. “On campus <strong>and</strong> online, toge<strong>the</strong>r we’re<br />

pioneering <strong>the</strong> science <strong>of</strong> this field,” says Kearns.<br />
