The mobile phone is no longer just a personal telecommunications device, it is a window to multiple social spaces that are constantly in flux. Sites such as Facebook and Twitter are accessed throughout the day by mobile users, as they tune in to their different networks and share updates and images.

What are the social impacts of this sustained engagement and continual presence? What does it mean for friendships and relationships?

In her lecture this week at UNSW - Always with me: How mobile and social media are changing us - Associate Professor Kate Crawford will share preliminary findings from the largest study of mobile media use in Australia and consider the complex terrain between humans, mobiles and social networks.

"The mobile phone has been undergoing a transformation in Australia: calling people is no longer its primary function. It has gradually become a powerful social portal that alters how we make and consume media," she says.

Based at the Journalism and Media Research Centre at UNSW, A/Prof Crawford is an ARC Discovery Research Fellow. Her books include the award-winning Adult Themes (2006). This year, she was an invited research fellow at Microsoft's Research Labs in Boston.

The lecture is presented by the Faculty of Arts and Social Sciences as part of its So, What? public lecture series.
