Dr. Keenan's prior work characterized gallium-containing bioactive glasses and their composites with polymer hydrogels, evaluating these materials against fibroblasts, osteoblasts, osteosarcoma, and myeloma cells, as well as bacterial and fungal testing. Current research includes incorporating phosphorous into glasses to enhance hydroxyapatite deposition and antimicrobial properties, synthesizing ISO 23317-compliant bioactive glasses, and developing rigid natural polymers for bone void-filling applications. He also explores ceramic surface functionalization and additive manufacturing of composites for biomedical uses.

Recent publications highlight his work on antimicrobial properties of bioactive glass composites, hydroxyapatite deposition, in vitro cytocompatibility, ion release mechanisms, and polymer-glass interfaces. His research spans materials optimization for clinical applications, including infection prevention and scaffold development.
