About the speaker

Dr Simon Gant
Technical Fellow @ HSE Science and Research Centre
Dr Simon Gant is a Technical Fellow in the Fluid Dynamics Team at the Health and Safety Executive with a master’s degree in Mechanical Engineering from the University of Leeds and a PhD in turbulence modelling from the University of Manchester.
He has been involved in safety-related research activities since 2005, including topics such as anhydrous ammonia (Jack Rabbit III), CFD modelling of atmospheric dispersion, carbon capture and storage, repurposing the gas distribution network for hydrogen transport, and many more.
He is currently the Chairman of the Atmospheric Dispersion Modelling Liaison Committee (ADMLC), an independent body that helps to coordinate research activities on atmospheric dispersion across the UK government. Dr Gant has published over 100 conference and journal papers and is a regular speaker at atmospheric dispersion and process-safety-related conferences.

Dr Shona Mackie
Senior Research Engineer @ Gexcon
Dr Mackie holds a PhD in Geosciences, awarded by the University of Edinburgh. She has 12 years of experience in research in various fields in academia and industry, which have included developing and analysing large models to predict renewable energy production, model radiative transfer for Earth observation, predict and monitor volcanic ash hazards, and project future climate.

Lorenzo Mauri
Principal Research Engineer @ Gexcon
Lorenzo has a background in Environmental Engineering and 15 years of experience with the development and application of simulation engines in the fields of gas dispersion and consequence analysis. His main research interests include atmospheric flows, multiphase flows, and gas explosions.
Lorenzo has extensive experience in software development and scientific programming. He has made substantial contributions to the recent development of FLACS and associated utilities, including the Ewan and Moodie release model, entraining leaks functionality, modelling of aerodynamic roughness, and others. He has developed FLACS’s Multiphase Drift Flux solver to simulate droplet vaporization and deposition.
In the last 3 years, Lorenzo has authored 4 publications in peer-reviewed journals. He is part of the International Conference on Hydrogen Safety – 2021 scientific committee. Lorenzo has been working in Gexcon for 7 years developing and using FLACS for consequence analysis and dispersion modelling.
