Takeshi Shirabe

Ph.D, University of Pennsylvania, USA
Master of City and Regional Planning, University of Pennsylvania
Bachelor of Engineering, Department of Naval Architecture and Ocean Engineering, University of Tokyo, Japan

Prior to joining KTH’s Department of Urban Planning and Environment in 2010, Takeshi was Assistant Professor in the Department of Geoinformation and Cartography at the Vienna University of Technology, Austria (2003-2010) where he received his Habilitation in Geoinformation.

Takeshi has served as a committee member for a number of conferences on Geographic Information Science including the International Conferences on Geographic Information Science (since 2006) and the AGILE International Conferences on Geographic Information Science (since 2007).
