Dr Lisa Ottenhaus is a structural engineer and senior lecturer, with expertise in design of timber connections. Lisa's research interests encompass the theory, analysis, design and performance of timber connections, including detailing for timber durability. Lisa and their team research offsite timber construction using both engineered wood products and light timber framing, design for adaptability, disassembly and reuse, and reversible timber joints.

Lisa holds a PhD from the University of Canterbury, Aotearoa New Zealand, on the seismic performance of connections in tall timber buildings, a Masters of Science in structural engineering from Delft University of Technology, and a Bachelor of Science from Karlsruhe Institute of Technology.

As part of the ARC Advance Timber Hub, Lisa co-leads Node 3 on Extending Building Life, and project 1.2 on timber connections. Lisa is a steering committee member of WG1 a COST Action Helen (Holistic Design of Taller Timber Buildings), and a founding member of the International Association for Mass Timber Construction.

Lisa is a committee member of TM-010 (Australian Standards technical committee on Timber Structures and Framing), and a steering committee member of the Australian Timber Construction Educator Network.

Lisa has been an invited speaker at the prefabAUS Offsite conference, the Brisbane Architecture and Design Festival, the International Holzbau Forum (Innsbruck, Austria) and has been interviewed by the Guardian, ABC Radio, Built Offsite, and the Holzmagazin.

Dr Felix Wiesner is an Assistant Professor at the University of British Columbia and an Honorary Fellow in the School of Civil Engineering at The University of Queensland and works as part of the National Centre for Timber Durability and Design Life. He was appointed at UQ as a Lecturer in Timber Engineering in 2019 to lead research projects focused on enhancing the fire performance of timber using treatments and modification techniques. His background is in structural fire engineering and the fire safety of timber structures, specifically engineered timber structures. His field of expertise are the critical evaluation of load bearing capacity of building elements in fire and the assessment of safety implications arising from the use of engineered timber as structural members in tall buildings or structures with extraordinary architectural features.

Dr Wiesner completed his Master of Engineering in Structural and Fire Safety Engineering at The University of Edinburgh from 2010 to 2015 before he successfully completed his doctoral studies on the structural behaviour of cross-laminated timber in fire between 2015 and 2019. During his undergraduate and postgraduate work, he closely worked with Arup on multiple projects regarding the fire safety of timber buildings and the effect of localised fires in large open spaces. He actively participated in the European COST Action FP 1404 for the Fire Safe Use of Bio-Based Building Products between 2016 and 2019, representing the UK as a Management Committee member. He significantly contributed to the success of the Fires in Tall Timber Structures: Large-scale Tests in Support of Tall Timber Construction project at the BRE in the UK and also worked as a member of the global Fire Safe Use of Wood research collaboration.

I have a multidisciplinary background in chemical and civil engineering, chemistry and materials science. Currently, I am the UQ leader of the National Centre for Timber Durability and Design Life, based at USC. I apply my expertise to understand the effects of fungal decay and moisture intrusion in timber connections, as well as the improvement of the fire performance of timber. I supervise 6 PhD students.
