Professor Daniel J Kelly

Professor (Mechanical & Manuf. Eng)

Dr Daniel Kelly is a Professor in the School of Engineering in Trinity College Dublin and Director of the Trinity Centre for Bioengineering. In 2008 he was the sole recipient of Science Foundation Ireland's President of Ireland Young Researcher Award (PIYRA). In 2009 he received a Fulbright Award to take a position as a Visiting Research Scholar at the Department of Biomedical Engineering in Columbia University, New York. In 2010 he was awarded a European Research Council starter grant of €1.5 million to develop novel stem cell and biomaterial based therapies to regenerate damaged articular cartilage. In 2013 he was awarded a €1.7m Principal Investigator grant from Science Foundation Ireland to develop novel tissue engineering approaches to treat degenerative joint disease. He was recently awarded an ERC consolidator grant of €2,000,000, making him one of the few PIs to have received two such awards from the European Research Council. Dr. Kelly leads a large multidisciplinary orthopaedic tissue engineering group based in the Trinity Centre for Bioengineering. The goal of his lab is to understand how environmental factors regulate the fate of adult stem cells. This research underpins a more translational programme aimed at developing novel biomaterial and mesenchymal stem cell (MSC) based therapies to regenerate damaged and diseased orthopaedic tissues such as articular cartilage and bone. To date he has published over 115 articles in peer-reviewed journals.

Articular cartilage tissue engineering: Dr. Kelly's lab is pioneering the use of adult stem cells isolated from synovial joints such as the knee, combined with bioreactors to mechanically stimulate these cells, to tissue engineer functional cartilage grafts. They have demonstrated that it is possible to engineer zonally organised tissues such as articular cartilage by recapitulating the gradients in regulatory signals that during development and skeletal maturation are believed to drive spatial changes in stem cell differentiation and tissue organization. They are also developing single stage therapies for articular cartilage regeneration that combine biomimetic scaffolds with freshly isolated stromal cells sourced from patients in-clinic. Bone, joint and limb regeneration: Dr. Kelly's lab have also demonstrated how complex tissues, such as the bone-cartilage interface, can be regenerated by designing tissue engineering strategies that recapitulate aspects of the normal long bone developmental process. They have also been able to scale-up this process to tissue engineer entire new bones. They are currently extending this strategy to tissue engineer whole joints using adult stem cells and 3D bioprinting. Stem cell mechanobiology: Dr. Kelly's lab is investigating how extrinsic mechanical cues can regulate stem cell fate. His lab has also identified novel roles for both mechanical signals and oxygen in regulating chondrogenesis and hypertrophy of MSCs.
