“I’m really bad at navigating public transportation,” she said. “When I got here I didn’t know what to do.”

That has not stopped Galvin from helping thousands of shuttle users, who are grateful for her assistance.

“I’ve gotten a lot of e-mails from guys saying, ‘Hey, that was really gutsy,’” Galvin said. “I don’t see gutsy. I see self-promoting.”

Galvin’s main activity at Harvard has been theater, but she has never done any modeling. She said she hates getting her picture taken.

Her mother, Boylston professor of rhetoric and oratory Jorie Graham, was initially confused by Galvin’s involvement with the website.

Once Galvin explained that this would not turn into a career, Graham was much more supportive.
