Walter is broadly interested in global biodiversity science. His research is interdisciplinary and combines elements of biogeography, community ecology, landscape ecology, macroecology, global change ecology, evolutionary and comparative biology, biodiversity informatics and conservation. Study systems include terrestrial vertebrates, in particular birds, and plants. Work in his research group attempts to integrate across scales of geographical, phylogenetic and ecological organization.
