Elkhoury’s research focuses on organ engineering and bioprinting, tackling the critical scarcity of transplantable organs in modern medicine. Using bioprinting technology, Elkhoury constructs complex living tissue that closely mimics natural organs. This precision in tissue architecture is crucial for ensuring functionality and biocompatibility, ultimately addressing the urgent need for viable transplantable organs. His doctoral research on 3D bioprinting of nanocomposite polymers for tissue engineering applications earned him a Best Thesis Award and the European Doctorate Label. He is in the process of filing a provisional patent in the U.S. and a PCT application through NYU's patent office.
