For the last couple of years, we have had the pleasure of having Klaus H. Ostenfeld as an external lecturer in the Bridge Design Course. From 2021, Klaus H. Ostenfeld will be an honorary professor at Aarhus University, and part of our group. Thereby becoming a permanent part of the lecturer team at the Department of Civil and Architectural Engineering.

Thomas Kabel has defended his PhD: "Mapping Breaking Ocean Waves using Novel LIDAR Equipment" on January 26th 2021. The defense were held primarily on ZOOM, with only Professor Georgakis and Julie from the group attending, due to the current situation. The opponents, Professor Chris Blenkinsopp (Uni. of Bath, UK) and Professor Normann Hoffmann (TUHH, Germany) approved the defense after numerous questions.
The PhD-abstract is available on his PURE-page. The report can be requested from the library.
Thomas Kabel continues his work within academia, and are staying on as a Post Doc within the group.

The online news media CHEDDAR has made a video explaining why cable-stay bridges took so long to catch on and why they are the new go-to bridge for engineers. In the video, our very own Professor Christos Georgakis supports the journalist with facts and know-how, alongside Project Manager David R. Capobianco, who oversees the construction of the Gov. Mario M. Cuomo Bridge in New York.

Marius Tarpø has defended his PhD: "Stress Estimation in Offshore Structures" on October 13th 2020. The first defense with people tuning in both live and on Zoom. The opponents liked the amount of work Marius had put into the project and approved his results.
The PhD-abstract is available on his PURE-page. The report can be requested from the library.
Marius Tarpø has continued his work within academia by joining the group of Professor Rune Brincker at DTU BYG.

During his PhD, Lubomir Matejicka has conducted a comparative study on ice-shedding properties of bridge cables with wire meshes. This has been done in the wind tunnel at Force Technology in Copenhagen, Denmark. The tunnel allows for accumulation of ice on the bridge cables.
The report can be found here.
