Dr. Elizabeth Cosgriff-Hernandez is a Professor of Biomedical Engineering at University of Texas at Austin. She received a B.S. in Biomedical Engineering and Ph.D. in Macromolecular Science and Engineering from Case Western Reserve University under the guidance of Professors Anne Hiltner and Jim Anderson. She then completed a UT-TORCH Postdoctoral Fellowship with Professor Tony Mikos at Rice University with a focus in orthopaedic tissue engineering. Dr. Cosgriff-Hernandez joined the faculty of at Texas A&M University as an Assistant Professor in 2007 and the University of Texas at Austin with the L.B. (Preach) Meaders Professorship in Engineering in 2017. Her laboratory specializes in the synthesis of hybrid biomaterials with targeted integrin interactions and scaffold fabrication strategies (e.g. injectable foams, 3D printing emulsion inks, reactive, in-line blending electrospinning). She also serves on the scientific advisory board of ECM Technologies and as a consultant to numerous companies on biostability evaluation of medical devices. Dr. Cosgriff-Hernandez is an Associate Editor of the Journal of Biomedical Materials Research, Part B, Fellow of AIMBE, and chair of the NIH study section on Musculoskeletal Tissue Engineering

Emulsion Inks for 3D Printing of High Porosity Materials

Our lab has developed a new solid freeform fabrication (SFF) technology capable of printing curable emulsion inks to print materials with hierarchical porosity. Briefly, an emulsion ink based on a high internal phase emulsion (HIPE) is deposited layer-by-layer using an open source 3D printer equipped with a syringe and motor-actuated plunger. Emulsions inks are rapidly cured after deposition by constant UV irradiation to form rigid constructs with interconnected porosity in a method we term Cure-on-Dispense (CoD) printing, Figure 1. 3D printed polyHIPE constructs benefit from the tunable pore structure of emulsion templated materials and the fine control over complex geometries of 3D printing that is not possible with traditional manufacturing techniques. Overall, the demonstrated ability to print porous materials using emulsion inks and CoD technology advance current additive manufacturing efforts to generate custom porous materials for tissue engineering and drug delivery applications.
