Keynote Speakers 2025
Daniel Joyeux, Efectis Group, France
Dr Daniel Joyeux is the chairman of Efectis Group dedicated to fire safety testing, certification, and engineering with more than 300 employees and 6 fire laboratories. He is an active member of numerous standardization and pre-standardization groups, as NFPA 502 for fire safety of tunnel, AFCEN for fire safety in Nuclear Plant, but also working groups from French ministries for regulation evolution. He is the convenor of the CEN TC127 WG8 “Fire Safety Engineering”. After a PHD on soot formation in 1993, he is working since 30 years on the FSE development and fire safety improvement. For 5 years, he has been Fire Expert of Justice at the Paris court of appeal.
Keynote: Structural safety in tunnel fires
Haukur Ingason, Research Institutes of Sweden (RISE), Sweden
Prof Haukur Ingason has over thirty years of international experience in fire safety research and engineering. He has been involved in large scale and model scale studies of fire and smoke spread in tunnels since 1992 and is one of the authors to the Tunnel Fire Dynamics handbook. He is an adjunct professor at Lund University, where he is supervising and giving classes for students on fire dynamics in tunnels and a senior research scientist at RISE Safety – Fire Research in Borås Sweden since 1988.
Keynote: Road map of tunnel fire research
Håkan Frantzich, Lund University, Sweden.
Dr Håkan Frantzich is a Senior lecturer (Reader) at the division of Fire Safety Engineering at Lund University. His main area of expertise is related to people safety during evacuation in tunnel fires. He has a great experience in experimental research on evacuation focusing on human behaviour and movement especially in combination with the use of technical installations. He has also been involved in applying risk assessment for fire safety verification. He has contributed to knowledge of evacuation design and risk assessment as an author of different publications e.g. design guides, building codes, a chapter on risk assessment in the current SFPE handbook of fire protection engineering and several journal and conference papers.
Keynote: Evacuation and human behaviours in tunnel fires
Igor Maevski, Jacob, USA
Dr Maevski is a Jacobs Engineering Global Tunnel Fire and Life Safety Lead with 40 years of experience in tunnel ventilation and tunnel Fire and life safety systems design and analysis. He is a Licensed Professional Engineer in the US, ASHRAE Fellow; Chairman of ASHRAE Standard Committee 217 on “Non-Emergency Ventilation in Enclosed Road, Rail and Mass Transit Facilities”, Principal Member of NFPA 502 Technical Committee since 2004. He is the author of numerous papers and several publications on tunnel ventilation and fire life safety including the Transportation Research Board (TRB) Synthesis Study – Design Fires in Road Tunnels; author of Recommended AASHTO Guidelines for Emergency Ventilation Smoke Control in Road Tunnels; author of the NFPA Fire Protection Handbook Chapter 10 Section 21 “Road Tunnels and Bridges; and Contributor to the ASHRAE Applications Handbook 2023 edition.
Keynote: Engineering practice of tunnel fire safety
Jie Ji, University of Science & Technology of China, China
Jie Ji is a Professor and Vice Director of the State Key Laboratory of Fire Science, University of Science & Technology of China. Prof. Ji has dedicated himself to the fire prevention and control of complex buildings, including high-rise buildings, tunnels, subways, and ancient structures. Till now, he has authored two monographs on tunnel fires and high-rise building fires, along with over 170 papers. In addition, Prof. Ji is the Fellow of The Combustion Institute and serving as a member of the editorial board of Fire Safety Journal, Fire Technology and Building Simulation. Research results have been adopted by more than 10 building fire codes both at home and abroad, and applied to enhance fire protection designs for many critical infrastructures in China.
Keynote: Flame behaviors and smoke transport in urban road tunnel fires under natural ventilation conditions
Jennifer Wen, University of Surrey, UK
Prof. Wen joined the School of Mechanical Engineering Sciences, University of Surrey as Professor in Energy Resilience in January 2023. She leads the Fire and Explosion Modelling Group (FMEG) at Surrey, and also "Energy and Environment Programme" at the pan-university Institute for Sustainability. Jennifer is a Fellow of the Royal Academy of Engineering and Fellow of the Institution of Mechanical Engineers. She is Chair of the UK Explosion Liaison Group (UKELG). Prior to Surrey, she held positions at Computational Dynamics Limited (founding vendor of STAR-CCM), British Gas plc, South Bank University, Kingston University London, and University of Warwick. Her research has been applied to a wide range of safety-critical scenarios. She has special expertise in modelling of accidental releases of flammable gases/liquid, the resulting fire, and explosions using the CFD code OpenFOAM. She is currently an Associate Editor for the Proceedings of the Combustion Institute, Vice-Chair Research for the International Association for Fire Safety Science (IAFSS). She also serves as a member and Task Force Leader of the European Safety Panel on Hydrogen Safety (EHSP) established by the Fuel Cell and Hydrogen Joint Undertaking (currently renamed as Clean Hydrogen Partnership) of the European Commission.
Keynote: Explosion hazards of vehicles with new energy carriers in tunnels and underground spaces
