John R. Underhill (born 5 January 1961)[1] is Professor of Stratigraphy and Director of the Centre for Energy Transition at Aberdeen University, Scotland.
His main area of geological research is understanding how the Sedimentary Basins form and evolve through the use of seismic interpretation methods.
One area of his interdisciplinary geo-research that has received recent acclaim has been an assessment of the geological, geomorphological and geophysical evidence for relocating Odysseus' Homeland, Ancient Ithaca.
Since retiring from the SPL, Underhill has retained an interest in refereeing through Masters Football, a televised indoor 6-a-side tournament which is played throughout the UK each summer and internationally in Dubai, Vietnam and Kuala Lumpur.
In 2009, he was one of the first referees to use video technology on live (Sky) TV to correctly disallow a goal and award a penalty for the opposition in the Masters Football Grand Final in the Liverpool Arena.
