BioMy research goal is to achieve comprehensive solutions to cardiovascular clinical challenges via chemistry approaches to produce tailorable materials that serve as scaffolds or therapeutic delivery vehicles that enhance tissue regeneration. I am a trained polymer chemist with expertise in biomaterials engineering for cardiovascular regeneration and nanomedicine. My graduate research experience, under the supervision of Peter X. Ma, focused on broadening the use of tunable tissue engineering scaffolds by developing polymers with chemical functionality that can be easily and rapidly fashioned into biomimetic physical constructs and activated with regulatory signals (biomolecules, peptides, and growth factors). I accomplished this by developing novel polymer synthesis methods that are cost-effective and facile to ease the path toward clinical translation. As a postdoctoral scholar, my current training is under the co-supervision of Prof. Sarah Heilshorn and Prof. Joseph Wu as a K99/R00 MOSAIC Fellow. My work entails the development of tailored injectable hydrogels for the local delivery of therapies after a myocardial infarct.

BioI have been engaged in the study of mechanical properties of materials for nearly 50 years. My early work was on high temperature creep and fracture of metals, focusing on techniques for measuring internal back stresses in deforming metals and featuring the modeling of diffusional deformation and cavity growth processes. My students and I also studied high temperature dispersion strengthening mechanisms and described the effects of threshold stresses on these creep processes. Since the mid-1980's we have focused most of our attention on the mechanical properties of thin film materials used in microprocessors and related devices. We have developed many of the techniques that are now used to study of thin film mechanical properties, including nanoindentation, substrate curvature methods, bulge testing methods and the mechanical testing of micromachined (MEMS) structures. We are also known for our work on the mechanisms of strain relaxation in heteroepitaxial thin films and plastic deformation of thin metal films on substrates. In addition we have engaged in research on the growth, characterization and modeling of thin film microstructures, especially as they relate to the development of intrinsic stresses. Some of our recent work dealt with the mechanical properties of nanostructures and with strain gradients and size effects on the mechanical properties of crystalline materials. Our most recent work deals with the mechanical properties of lithiated nanostructures that are being considered for lithium-ion battery applications.
