My first trip after the virus is as Expedition leader in Tasmania with Coral Expeditions (March), followed by my role as biologist guest lecturer on the Great Barrier Reef (April) and Expedition Leader in the Kimberley (in May). If you can't go travelling until everything settles down, then until then, here I am doing online guided walks for Noble Caledonia and online lectures for Silversea.
