Ryan Gregory

Ryan Gregory is a Professor at the University of Guelph, specializing in genome evolution and the C-value enigma. His research integrates genomics, cytogenetics, and organismal biology to explore genome size variation across taxa. Gregory holds a B.Sc. from McMaster University (1997) and a Ph.D. from the University of Guelph (2002), followed by postdoctoral fellowships at the American Museum of Natural History (2002–2003) and The Natural History Museum, London (2003–2004).

His work focuses on comparative analyses of genome size patterns in invertebrates and vertebrates, emphasizing the ecological and evolutionary implications of genomic diversity. He pioneered the Animal Genome Size Database and develops DNA quantification methods, including image analysis and flow cytometry. Gregory advocates for interdisciplinary collaboration, bridging fields like genomics, ecology, and paleontology.

Recent research trends include exploring transposable element dynamics, polyploidy in animals, and the integration of Indigenous epistemologies with neuroscience. He advises multiple graduate students and contributes to initiatives like the Biodiversity Institute of Ontario’s Genomic Diversity Division. His lab emphasizes global accessibility to genomic tools, particularly in biodiversity-rich, underfunded regions.
