Lisa-Mareike Ottenhaus

Lisa-Mareike Ottenhaus is a Lecturer in Structural Timber Engineering in the School of Civil Engineering at the University of Queensland. She completed her PhD at the University of Canterbury in New Zealand, where her doctoral research examined the seismic performance of connections in tall timber buildings, with a primary focus on cross-laminated timber (CLT) and laminated veneer lumber (LVL). During her PhD, she collaborated with XLam, a key supplier in the field, which was later acquired by Hyne Timber, enabling the launch of Australia's inaugural CLT production line. At the University of Queensland, Ottenhaus has shifted her research towards adaptable timber buildings engineered for disassembly and reuse at the end of their service life, thereby supporting circular economy principles within the construction industry. Her scholarly pursuits encompass the design and analysis of timber connections, factors influencing ductility and overstrength, reversible timber systems, and the structural performance of mass timber elements subjected to monotonic and cyclic loading conditions.

Ottenhaus's contributions to timber engineering are evidenced by her Google Scholar profile, which records over 667 citations. Notable publications include "Design for adaptability, disassembly and reuse – a review of reversible timber connection systems" (Construction and Building Materials, 2023), "Designing timber connections for ductility – A review and discussion" (Construction and Building Materials, 2021), "Structural performance of large-scale dowelled CLT connections under monotonic and cyclic loading" (Engineering Structures, 2018), "Overstrength of dowelled CLT connections under monotonic and cyclic loading" (Bulletin of Earthquake Engineering, 2018), "Mode cross-over and ductility of dowelled LVL and CLT connections under monotonic and cyclic loading" (Journal of Structural Engineering, 2018), and "Ductility and overstrength of nailed CLT hold-down connections" (Engineering Structures, 2020). She actively participates in international initiatives as a Steering Committee member of the Council on Tall Buildings and Urban Habitat (CTBUH) research project "The Future Potential of Steel-Timber Hybrid Structures," leads the adaptability theme of Working Group 1 in the COST Action "Holistic Design of Taller Timber Buildings," and serves as a founding member of the International Association for Mass Timber Construction, advancing advocacy and education on mass timber globally.
