Recipient of the College of Physical Sciences Award for Excellence in Teaching in 2017.
I am an academic in the School of Engineering at the University of Aberdeen. My primary research interests span across experimental/theoretical fluid dynamics in porous media and narrow channels.
The applications of such studies are in developing solutions for energy recovery from subsurface resources, energy storage, and minerals extraction.
In my group, we have expertise in materials science and electrochemistry application in mineral extraction, this is in collaboration with European companies and Universities.
I also work on developing solutions for hydrogen storage, carbon capture and storage (CCS), this includes optimisation and prediction of multiphase flow in surface facilities and subsurface storage capacities. The solutions also aim at decarbonisation of industry and clean energy storage.
I work closely with local and international research councils and industry from Africa, Middle East, and North America to address the current problems in the energy sector and explore future opportunities. In recent years, I have been managing/co-managing a range of research projects that attracted more than £500k external grants.
Key research areas in my group:
- Fluid flow in complex channels and porous media
- Mechanics of non-Newtonian fluids (Colloidal suspensions, Foams, Polymer solutions and Nanofluids)
- Chemistry of colloidal suspensions/emulsions/minerals and ionic transport with a focus on energy transition
I am currently accepting PhDs in Engineering.

Joe re-joined us in April 2017. He got his MSc in Reservoir Engineering form the School of Geosciences at the University of Aberdeen in November 2016. He previously studied Geophysics at Imperial College London where he discovered his interest in numerical modelling, and his current studies, he is developing models and tools for flow dynamics in hydraulically fractured rocks. He won the Best MSc thesis award in 2016.
Samuel Felix Ofesi
Samuel received his BSc and MSc degrees in Petroleum Engineering, from Abubakar Tafawa Balewa University, Bauchi (ATBU) and Federal University of Technology Owerri, respectively. Before joining our group, he worked as a lecturer in Federal University of Petroleum Resources, Effurun, a drilling engineer in SINOPEC/NPDC OML 64/66 swamp project. His PhD research project focuses on the characterization of oil-based foam drilling fluids, aiming at inventing an oil-based foam drilling fluid suitable for drilling high-temperature reservoirs and geothermal aquifers.
Tomi started his PhD in January 2023, he worked as a lecturer at Universitas Islam Riau (UIR) for 7 years before joining the University of Aberdeen. Tomi received his Master’s in Petroleum Engineering from Institut Teknologi Bandung (ITB) in Indonesia. He is currently studying the development of technologies for mineral extraction from petroleum and geothermal reservoirs, aiming to support the Energy Transition.
