Research Interest

Dr. McCann’s research in evolutionary cell biology focuses on the origins of multicellularity and how multicomponent cell adhesion complexes were essential during early animal evolution. Model organisms used for this work include the apusozoan Thecamonas trahens, amoebozans (cellular slime molds), choanoflagellates, and several cnidarians. He uses molecular and cellular techniques to identify how adhesome components interact with one another and a broad phylogenomic approach to correlate function with evolutionary conservation of protein-protein interaction domains in simple and complex adhesion assemblies. The goal of this research is to understand the fundamentals of multicellularity, with the expectation that this basic research may identify pathways in the pathology of cancer, which is characterized by the loss of multicellularity during cancer progression.
