 My white paper forecasts on geospatial technologies for the Institute for the Future's X2: The Future of Science and Innovation are now accessible Online. There are ten of them: I have placed links here (May 1, 2008)
 I was recognized with an award from the President and Director of the Association of American Geographers, at the AAG Awards Luncheon in Boston, in recognition of my NSF CAREER grant from 2007(April 19, 2008)
 I gave a talk on "Using geospatial agents and space-time GIS to model dynamic human geographies at very small scales" at the Annual Association of American Geographers meeting in Boston, as part of a session on "Dynamic GIS" (April 15, 2008)
 Wi-Fi Networking News has a nice piece on my Wi-Fi geography research: "Charting a landscape with Wi-Fi signals", Wi-Fi Networking News (Glenn Flesichmann) (April 14, 2008)
 Following an invitation from Fabien Girardin and Carlo Ratti, I gave an invited talk, "Modeling the real-time city", at the workshop on real-time cities at MIT's SENSEable City Lab (April 14, 2008)
