Research Hopper published his early research on the systematics and speciation of the family Haemodoraceae, including kangaroo paws (Anigozanthos), which formed the basis of his PhD at the University of Western Australia in 1978. He subsequently worked on the conservation, ecology, and taxonomy of Western Australian flora, including eucalypts, orchids, and plants of granite outcrops.

In the 1990s and 2000s, Hopper's research extended to plant biogeography and conservation management, emphasising the flora of south-western Australia. In 2009 he developed the OCBIL theory (old, climatically buffered, infertile landscapes), proposing evolutionary and ecological processes distinctive to ancient, nutrient-poor regions.

Honours On 1 January 2001, the Australian government awarded Hopper the Centenary Medal for his "service to the community". On 11 June 2012, Hopper was named a Companion of the Order of Australia for "eminent service as a global science leader in the field of plant conservation biology, particularly in the delivery of world class research programs contributing to the conservation of endangered species and ecosystems." He was also inducted into the Western Australia Science Hall of Fame in the same year.

Albany In 2015, he moved to Albany, Western Australia, and he has returned to his interest in Anigozanthus. In 2025 he published a book on the genus Eucalyptus that examines Aboriginal knowledge and Western Science relating to the genus.
