Xie Lab

The research interests for the Xie lab centers on the synthesis, surface modification and self-assembly of materials at nanometer scale to address problems in the field of tissue engineering, regenerative medicine and drug/gene delivery. Our research programs are built upon interdisciplinary subjects including materials science, engineering, biology and medicine. We develop novel, smart biomaterials with well-controlled composition, structure and functional properties. We employ analytical tools in materials science, biology and medicine to characterize these biomaterials as either scaffolds or drug/gene carriers. Specifically, we are interested in use of nano-structured materials together with signaling molecules to regulate cell/stem cell behaviors for regenerating various types of tissues. We are also interested in developing nanofibrous materials for topical delivery of therapeutic agents (e.g., antimicrobial peptides, chemotherapeutic drugs, cytokines and growth factors).
