In Brief:

Born in 1966 in Essen, Germany, he graduated at the University of Bochum in 1994 at the Faculty of Civil Engineering on non-linear action effects on industrial buildings. The subsequent research work on the field of building aerodynamics was conducted at wind-tunnel laboratories in France and Denmark and finalised in 2000 at the University of Bochum with a doctoral thesis about the influence of the simulation of the natural wind on the overload risk prediction of industrial buildings.

In 2000 Hans Holger Hundborg Koss continued his work in wind engineering, on both onshore and offshore structures, at the Danish Maritime Institute, which today is the Division of Maritime Industry of FORCE Technology. His work covered areas such as the determination of design wind loads on engineered structures and their static and dynamics response to wind, flow-induced vibration and fatigue, experimental fluid mechanics, wind-related environmental issues such as pedestrian wind comfort and occupancy comfort of buildings subjected to vibrations, architecture and maritime aerodynamics.

In 2005 he started teaching as an external lecturer in a special course on seismic and wind engineering at the Technical University of Denmark (DTU). Since 2008 he has a position as Associate Professor at the Department of Civil Engineering BYG·DTU.
