Professional biography

Currently seeking PhD students interested in a low-carbon, circular economy: e.g., waste to energy, resource recovery!

Dr. Tarek Rashwan is currently researching a range of environmental engineering topics that support a low-carbon and circular economy, such as assessing hydrogeological conditions for safe used nuclear fuel storage, large-scale hydrogen storage systems, and scaling-up a novel thermochemical waste-to-energy technique based on smouldering combustion.  These projects primarily focus on understanding heat and mass transfer dynamics in porous media systems via experimental, analytical, and numerical methods.

The following image link is to SPLICE: Sustainable Processes Linked for an Integrated Circular Economy.  This is an Open Societal Challenges project linked to my team's core research activities. 
 

Please see this story on our 2023 research meeting, SPLICE 2023.

Teaching interests

I am engaged in supporting the presentation and production of various engineering and environmental & sustainability courses, including

Impact and engagement

My team and I engage frequently in external events.

See an example event below with myself and colleagues alongside OU PhD students Harri Williams and Marc Cochrane.  This panel discussion was on hydrogen in the UK and a part of Energy Security & Green Infrastructure Week 2023.

External collaborations

I have many long-standing collaborations with colleagues accross the UK - e.g., University College London, The University of Edinburgh, The University of Strathclyde - and internationally - e.g., Western University (Canada), York University (Canada), Universidad Técnica Federico Santa María (Chile), Federal University of Espírito Santo (Brazil), Xi'an University of Science and Technology (China), and China University of Mining and Technology (China). In addition, I collaborate frequently with multiple industry partners, including Nuclear Waste Management Organization, Geosyntec Consultants, Saietta, and the leading smouldering technology provider Savron.
