 Keerthan Poologanathan

Dr Keerthan Poologanathan is currently a Senior Lecturer in Structural Engineering at Northumbria University. Dr Poologanathan has more than 10 years of experience in R & D in steel structures (Cold-formed and Hot-rolled), thin-walled structures, optimization of steel sections, hollow flange beams, innovative steel products and systems, fire safety of buildings, light gauge steel frames, stainless steel, aluminium structures, lightweight concrete, enhanced plasterboard, phase change materials, thermal and mechanical properties at elevated temperature, modular building systems, advanced numerical modelling, genetic algorithm, energy performance of buildings, fibre composites for retrofitting and rehabilitation of structures. He has published more than 150 research papers. Since 2010 Dr Poologanathan have been working as a principal or an associate supervisor of 15 higher degree research students (12 PhD Students and 3 Masters Students). Dr Poologanathan’s current research projects have strong connections with the steel and concrete industry. He has worked closely with many industry partners, including: MMC Engineers, Intelligent Steel, EOS Facade, Etex, Promat, Cemex, Knauf Plasterboards, OneSteel Tube Mills, Henrob UK and Australia - Self Piercing Rivet Solutions for Manufacturers, etc. He is also BSI’s B/525/9 structural use of aluminium subcommittee member. His research on cold-formed steel beams now features in Australian codes of practice (AS/NZS 4600, 2018). Since 2012 He has secured 3 Australian Research Council (ARC) grants (More than one million AUD). He also secured number of research grants from industry partners (ERDF Industrial Intensive Innovation Programme (IIIP) with Lynx Precast, Collaborative PhD Project with MMC Engineers).
