trips during his degree at Cambridge. In 1974 he set off from the UK to Canada for his PhD at McGill University and has worked there ever since, except for research sabbaticals overseas. His co-authored book, A Geological Companion to Greece and the Aegean, explores the geology of archaeological sites, including aspects such as bedrock, building materials, earthquakes and volcanic eruptions. His current book project is on geology and the ancient wonders of the world. He recently joined us on our Light of Greece cruise, where we visited the sites of two of the ancient wonders: The Colossus of Rhodes, and The Temple of Artemis at Ephesus.
