Bridging the gap between theory and practice: New professor of timber and solid construction at TH OWL

At the start of the 2025/2026 winter semester, the Faculty of Civil Engineering at the Detmold campus will be enriched by the addition of a dedicated new member: Professor Dr. Johann Jakob Marx (37) will take over the field of timber and solid construction, bringing with him not only sound scientific expertise but also valuable practical experience from the world of engineering.

Born in Bielefeld, he studied structural engineering (Bachelor of Engineering) and then sustainable construction and management (Master of Engineering) at what was then the Ostwestfalen-Lippe University of Applied Sciences (HS OWL).

In 2020, he received his doctorate from the Technical University of Braunschweig with a thesis on the "Shear strength of loosely reinforced and prestressed masonry beams."

Parallel to his academic career, he gained extensive professional experience – including from 2011 to 2019 as academic staff in the section of solid construction and building materials at HS OWL, from 2018 to 2022 as a structural engineer at the engineering group "hmr," and since then as managing director of "hmr Ingenieure GmbH & Co. KG." Professor Marx gained international experience in 2010 at HOCHTIEF Qatar.

In his new role, the expert, who lives in Lemgo with his wife and two children, wants to bring his passion for practical teaching to bear and inspire students to take an interest in sustainable timber and solid construction. This includes the use of digital tools, the integration of prefabrication technologies, and interdisciplinary projects involving Architecture, Wood Technology, and Environmental Engineering.

For Marx, the professorship is the "ideal interface for practical research and transfer." His research focuses on hybrid construction methods, wood-wood connections, the load-bearing capacity of hybrid cross-laminated timber panels (HBSP), the use of recycled materials, and the optimization of load-bearing structures. 

"For me, research is a means of solving real problems in construction—in a resource-efficient, practical, and interdisciplinary way. It should take up ideas from practice and promote innovation," says Professor Marx. Close exchange with business, industry, and trade is particularly important to him in order to strengthen the bridge between theory and practice.

Sustainable construction not only shapes his professional work, but also his private life. In his free time, he devotes himself to craft projects, gardening, and the use of natural building materials such as clay. 

With his experience, creative drive, and enthusiasm for research and teaching, Professor Marx wants to actively shape the strategic development of the university—with a clear focus on sustainability, internationalization, and practice-oriented innovations.
