Today we’re “repeating” special guest. We enjoyed so much talking to Wenfei Xu anbout mobile phone data in our last episode (Episode 25: What we talk about when we talk about mobile phone data), that we decided to bring her on board again. But there’s a twist: this time, we’re returning to our “A day in the life of…” series, where we explore the behind-the-scenes view of what it is like to be a GLaD researcher.    Wenfei i Assistant Professor in the Department of Geography at the University of California, Santa Barbara. An urban planner by training, Wenfei has worked a lot with mobile phone data, but also has a super interesting story to how she arrived at that research interest. Come the fancy data, stay for engaging conversation about hopping between academia and industry, traversing disciplines, and… an Exhibitions entry in your CV.
