Dr Osman obtained an MPhil in 2002 and a PhD in 2005 from Cambridge University, both in geotechnical engineering. Dr Osman’s research focuses on developing analytical and numerical solutions for soil-structure interaction problems. His research has been funded by the RCUK, the Royal Society, the Royal Academy of Engineering and the British Council. He is currently leading the Newton Fund international consortium on Unsaturated Soils Mechanics for Engineering Practice (UnsatPractice).
Dr Osman is currently a member of the editorial board of the ICE proceedings- Geotechnical Engineering and he was a member of the Géotechnique Advisory Panel (Jan 2011-Jan 2014) and the Executive Committee of the UK Association of Computational Mechanics (2012-2014).
