Bernie was a geologist and geomorphologist specialising in landslides and volcanism, especially in the Newer Volcanics Province of Western Victoria, where he worked to map the regolith landforms that tell the story of Victoria’s past while determining future volcanic risk. He applied his expertise to the neotectonics of South-Eastern Australia, the recently-active and active volcanoes of the Pacific region, and the morphotectonics of the Central Victorian Highlands.
