Dr Jordan Phethean

About

As an Earth Sciences Lecturer within the School of Science, I dedicate myself to excellence in teaching and research across a diverse range of Earth and Environmental Science topics.

I bring my world-leading research into the classroom to inspire the next generation, unravelling the enigmatic tectonic origins of Iceland (the world's lost 8th continent!) and teaching students to model ultra-deep aquifer systems to secure drinking water for future generations - just as I do for the €1,000,000 Horizon Europe RESCUE research project...

Teaching responsibilities

I teach on a wide range of modules for our BSc Earth Sciences, BSc Environmental Sustainability, and MSc GeoEnergy degree programmes, including:

Advanced Earth Scientist's Toolkit (L4)
Sustainable Water Resources (L5)
Imaging the Earth (L6)
Modelling Earth Energy Systems (L6)
Subsurface Geology (L7)

I also supervise student research projects at BSc, MSc and PhD level.

In my strive for teaching excellence, I enjoy actively engaging in pedagogic research, which is currently focused on 'digital learning tools in the field'.

Research interests

My primary research areas include ultra-deep groundwater resources and plate tectonic theory. With a strong background in Earth sciences, geophysics, and numerical geodynamics, I am able to investigate Earth and environmental problems using a multi-disciplinary approach. Many of my current research projects are of interest to society, industry, and academia, including:

RESCUE: RESources in Coastal groundwater Under hydroclimatic Extremes - Understanding ultra-deep groundwater resources for the next generation
ICE: Icelandic Continent Exploration - Unveiling the world's lost 8th continent beneath Iceland

Whilst some of my research also address ongoing humanitarian crises:

SPRinG: Sourcing Potable Resources in Gaza - Drinking water exploration for Gaza's 2 million inhabitants

Further research interests include:

What is the role of the lithosphere in controlling plate motions?
What potential does the UK have for ultra-deep offshore geothermal energy?
Why do some continents break up 'magmatically' whilst others are 'magma-poor'?
Where really is the East African transform margin?
How and why do 'microcontinents' form?

My specific expertise includes: numerical groundwater simulations, plate tectonic modelling, gravity and potential field data, continental margin development, reflection seismics, GIS, geodynamic modelling, and structural geology.

Experience in industry

My PhD research was Sponsored by ENI, one of the 7 global energy supermajor corporations. During this project I worked closely with ENI, frequently visiting their head offices in Milan (Italy) for knowledge exchange and data interpretation.

International experience

Alongside working with many international research partners from Italy, Norway, Canada, France, China, Malta, Germany, and the USA as part of the RESCUE and ICE projects, I also undertake frequent remote research fieldwork campaigns in Iceland, Greenland, and elsewhere around the globe.
