Description of Research:
Our primary research has been focused on matrix mechanics to drive biomaterials translation for tissue engineering and regenerative medicine applications. Current interests are focused on developing regenerative strategies for bone and skeletal muscle tissue engineering. We are specifically interested in the 3D architectures of porous materials, the use of biophysical stimulation using bioreactors and the use of micro computed tomography as a modeling tool. Specific applications being developed in the lab include hydroxyapatite ceramics for bone, vascularization in hydrogels for bone and skeletal muscle, composite structures for laryngeal reconstruction, bioreactors developed for ligament and dental restorative research and organoid evaluation for salivary gland and pediatric cancer drug discovery.
In support of the tissue regeneration efforts, our lab focuses on the correlation of in vivo bone and vessel morphology using micro computed tomography and computational biomechanics analyses to scaffold structure and matrix properties. The evaluation of mechanical properties along the translation of the scaffold from material synthesis, through in vitro testing and in vivo evaluation provides a powerful predictive analysis tool with built in feedback for design improvements. Similarly, the lab develops bioreactor models and surgical support infrastructure and instrumentation for the delivery of novel therapeutics. This includes applications in targeted drug delivery as well as minimally invasive surgical platforms.
Specifically, on-going projects focus on the employment of mechanical stimulation regimes in bioreactors to improve engraftment of bone and muscle substitutes. The compliance of substrates has a profound influence on the stem cell response and this effect is enhanced by applied mechanical loads. Studying the relative impact of these cues on directed cellular differentiation is important to develop appropriate materials for musculoskeletal interfaces, where there is a steep gradient in mechanical properties. Our research has been supported by the National Science Foundation (NSF), National Institutes of Health, the Department of Defense, and various private foundations and multiple collaborative projects with industry.
