Deans' research spans diverse topics including:
- Taxonomic revisions of gall wasp species complexes
- Development of GallOnt, an ontology for plant gall phenotypes
- Biogeographic studies of Hymenoptera in Canada, Alaska, Greenland, and Central Asia
- Ecological interactions such as ant dispersal mechanisms in oak galls
- Extreme defensive adaptations in cynipid galls
- Cultural entomology through arthropod references in haiku
His recent publications (2022-2025) emphasize integrative taxonomy, with 22 new Ceroptres species described, and novel insights into gall induction mechanisms through venom gland anatomy. Collaborative works highlight global biodiversity patterns and ecological convergence between plant seeds and insect galls.
Deans' lab has been featured in media outlets for groundbreaking discoveries, including a child's backyard observation that reshaped understanding of insect-plant interactions and a newly identified defense strategy in gall wasps. He contributes to DNA barcoding initiatives and develops standardized frameworks for gall phenotype documentation.
