I am Professor at TU Darmstadt and lead the Remote Sensing and Image Analysis Group. My research interests focus on sensor fusion, semantic labeling, deep learning, 3D reconstruction, pattern recognition, IR-thermography, and crowdsourcing. In my PhD thesis, entitled “Automatic texturing of 3D models of urban areas using image sequences from airborne TIR cameras” I investigated, among others, the influence of statistical uncertainties on the co-registration of 3D building models and thermal image sequences. I also worked with data fusion, including fusion of hyperspectral images with digital surface models, multi-scale fusion of thermal images, smartphone data fusion as well as on semantic labeling and creation of 3D indoor models. In the first half of 2018 I was on sabbatical leave at the Ohio State University in Columbus, Ohio, USA working on the project “From Point Clouds and Images to Semantic Information: A Case Study for Indoor-Outdoor Building Modeling”. Subsequently, I continued my research work on semantic labeling, deep learning and indoor-outdoor mapping at the Technical University of Munich.
