My dissertation work focuses on the application of FRESH 3D bioprinting (using collagen and extracellular matrix) to the engineering and construction of large-scale tissue constructs for use as diagnostic and regenerative treatment tools. In addition to printing these constructs I design and build the majority of the hardware utilized to print them, including the printing platforms, the printing-specific syringe pump extruders, and a wide array of electromechanical experimental apparatus, all of which have been published or are pending publication in open-source hardware journals.
The primary targets of my research are patient-specific tracheal grafts and volumetric muscle loss tissue replacements for the treatment of congenital malformations and trauma, in process assessment and regulation of 3D bioprinting for standardization towards effective clinical translation, and in vitro collagen microfluidic models for use as research models and clinical diagnostic tools. I have orally presented the results from several of these projects at multiple national conferences including BMES, SFB, S3BC, and Biofabrication. In addition to my primary research, I have contributed to a significant body of collaborative research in the fields of biomechanics, biosensing, cardiac tissue engineering, novel bioink synthesis, and synthetic material printing. I have also successfully applied for and received an NIH F30 through the NHLBI for my research on tracheal grafts.
