Prof. Dr.-Ing. Timo Balz

Timo Balz was born in Stuttgart, Germany. He received the Diploma degree (Dipl.-Geogr.) in geography and the Doctoral degree (Dr.-Ing.) in aerospace engineering and geodesy from the Universitaet Stuttgart, Stuttgart, in 2001 and 2007, respectively.

From fall 2001 to the end of 2007, he was a Research Assistant with the Institute for Photogrammetry, Universitaet Stuttgart. Between 2004 and 2005, he was a Visiting Scholar with Wuhan University, Wuhan, China. From 2008-2010, he has been a Postdoctoral Research Fellow with the State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing (LIESMARS), Wuhan University. From 2010-2015 he was Associate Professor for Radar Remote Sensing with LIESMARS. Since 2015 he is Full Professor with LIESMARS.

He serves as Associate Editor for Remote Sensing and the Journal of Geodesy. He is a member of the Editorial Board of Geo-Spatial Information Science. Since 2016 he is Chair of the ISPRS Commission I Working Group on SAR and Microwave Sensing. He has authored and co-authored more than 150 scientific articles in journals, books, and conference proceedings.

Timo Balz’s research focuses on applying Synthetic Aperture Radar data for measuring surface motion and surface-cover changes over time to better understand our dynamic Earth. Understanding today’s Earth dynamics also requires us to better understand the past and therefore I am also working on using SAR Remote Sensing for landscape archaeology.
