Bob Gaines, a recipient of 2007 and 2013 Wig Awards for excellence in teaching, offers courses in Earth history, sedimentology, paleontology and climate change. His research focuses on the Cambrian Explosion, the flowering of complex life on Earth during the Late Neoproterozoic and Cambrian Periods some 570 to 500 million years ago. Bob works on the Burgess Shale and many other deposits like it that contain an unusually-rich fossil record of this event. He is also interested in microbial-mineral interactions as a link between the geosphere and the biosphere. He studies ancient sedimentary rocks in South China, British Columbia, Morocco and across the USA, especially the Great Basin.
