Research Interests:

Dr. Jayasuriya is a Professor in the Department of Orthopaedic Surgery at the University of Toledo. Dr. Jayasuriya also has an adjunct faculty appointment with the Department of Bioengineering at the University of Toledo. Dr. Jayasuriya’s laboratory currently investigates injectable bone graft devices to regenerate or repair damaged human bone tissues. These injectable bone grafts mainly manufactured using natural polymer biomaterials including chitosan biopolymer. The major advantage of injectable graft is that it can be applied to bone defect site via an arthroscopically, a minimally invasive procedure used in orthopaedics. Injectable bone graft devices are evaluated for biocompatibility, biodegradation, and mechanical testing using in vitro and in vivo studies. New bone formation with bone grafts are assessed using a rat model craniomaxillofacial bone defects which treated using bone graft devices over time. The new bone tissues are evaluated using histology, histomorphology, Raman, micro-CT, and mechanical analysis. In addition to bone regeneration studies, Dr. Jayasuriya’s laboratory also focuses on delivery of drugs, antibiotics, growth factors, and cells.
