Actress EVA LONGORIA visited a Pennsylvania university on Wednesday (10Oct12) to talk to students about her career and activism.

The Desperate Housewives star appeared onstage in the packed auditorium at the University of Pennsylvania's Wharton School for her 'social impact' lecture, discussing her efforts to bring attention to pressing problems, including immigration.

Longoria took to her Twitter.com page to share photos of herself at the event, and even sent messages to guests who had attended her talk.

She tweeted, "Thank you Wharton-University of Pennsylvania for having me speak today! I'm so inspired by all the students I spoke to!"
