2014 – now, Assistant Professor, Mary & Dick Holland Regenerative Medicine Program and Department of Pharmaceutical Sciences, University of Nebraska Medical Center. Xie laboratory’s research interests center on the synthesis, surface modification, 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 including tendon-to-bone insertion site, cartilage, bone, skin, cardiac muscle, and nerve. We are also interested in developing nano-structured materials for enhancing survival, proliferation, and function of human islets in vitro and in vivo. Additionally, we are interested in developing nanofibrous materials as local drug delivery devices for prevention of surgical site infection.
