After graduating with a degree in Geology and Earth Science from Strathclyde University in 1986, Iain obtained a doctorate from the University of Bristol. His doctorate included research into earthquakes, a subject which he would go on to present in his later television career.


Iain got the chance to make his television re-appearance in 2002 with Horizon's Helike - The Real Atlantis as an expert academic, using his expert geological knowledge.

Enjoying this foray back into television, Iain strove to present geology to the masses and went on to appear as a team member in Rough Science, a series where a group of scientists with modest supplies must solve tasks using only the tools and resources at hand.

This early television presenting and contribution work paid off when he landed the 2007 series Earth: The Power of the Planet. This was followed by Ten Things You Didn't Know About... and How the Earth Made Us. Airing in 2010, How the Earth Made Us chronicled how the different aspects of our planet shaped us throughout our past.

Iain went on to win the Ness Award from the Royal Geographical Society in 2010 and has more recently presented the stunning How to Grow a Planet.
