Tom Sharpe

Originally from Glasgow, Scotland, Tom is a graduate of the universities of Glasgow and Leicester and has spent the last 35 years as a geology curator in the National Museum of Wales. He is a Chartered Geologist, a Fellow of the Geological Society, and a Fellow of the Royal Geographical Society, as well as a member of a dozen other geological and polar societies. Tom has over three decades of experience of interpreting geology for a wide range of audiences, through talks, lectures, field trips, exhibitions, and publications. He has curated a number of highly regarded geological and Antarctic exhibitions, and was involved in the planning of events to mark the centenary of Captain Scott’s South Pole Expedition.

He has also taught lifelong learning geology classes for over 25 years at Cardiff University and led field trips around Britain and throughout the western United States, the North Atlantic, and in the Mediterranean region. Fieldwork and teaching have taken him to many parts of the world, and he was closely involved in the setting up of new geological museums in Newfoundland and in the United Arab Emirates. He lectures frequently to, and leads field trips for, various groups around the UK and on expedition cruises to the Arctic and Antarctic and other parts of the world.

He has interests in dinosaur trackways, as well as in the growth of geology in the early 19th century, in particular the discovery of Jurassic marine reptile fossils, the development of the first geological map, and in the foundation of the British Geological Survey and the life and work of its first director. He also has a particular interest in the development of the understanding of Antarctica’s geology and in the work of the geologists on Heroic Age expeditions.

The co-author of a successful geology field guide to South Wales, Tom is currently writing a biography of the 19th-century geologist Sir Henry De la Beche, a study of the geological maps of William Smith, and several new field guide books.
