My research focus is on the use of photogrammetry in the AEC industry and infrastructure inspection. A special focus is currently on the autonomous navigation and mapping using SLAM and NBV. I am also working on the development of educational materials for the UAV center of the ITC faculty and contributing to capacity-building projects of the center. Furthermore, I am experienced in the topic of adjustment computations and theory of errors and wrote a book in this field.Technical areas of expertise:

  • Photogrammetry and geometric computer vision.
  • Autonomous mapping and navigation
  • Adjustment computations.
  • Mobile mapping systems and Lidar technology.
  • Surveying engineering.
