RESEARCH

As a principal scientist in SWRI, Dr. Cheng develops new technology platforms and expands existing capabilities on biomedical material engineering. His areas of research interest include nanomaterial, biomaterial, tissue engineering, nanomedicine and regenerative medicine, and medical device. His research interests emphasize on developing synthetic soft and hard biomaterials (polymer hydrogel, bioceramic, and composites) and natural biomaterials (e.g., collagen, chitosan) for a wide range of applications such as drug/gene/vaccine delivery for prevention or treatment of diseases, wound healing and tissue engineering, bone grafts, and biosensors. He also supports the program and clients by using the experience in cell culture (cancer cells, bone marrow stromal cells, fibroblasts), animal and human subjects tests, and general biomaterial and tissue evaluation and testing. 

At SwRI, Dr. Cheng has been a principal investigator/project manager on multiple projects including multifunctional, aligned collagen for tendon/ligament repair; Mg alloy for bone tissue engineering; antimicrobial/biocidal testing of compounds and devices; magnetic calcium phosphate nanoparticles; medical device development; and microencapsulation of drugs/actives and particulate adjuvants for vaccines. He has been a key contributor to several programs including bone-targeting nanoparticles; antimicrobial, anti-abrasion coating on orthopedic implants; haemoglobin encapsulation; collagen-hydroxyapatite perfusion scaffold for mesenchymal stem cell expansion; aligned carbon nanotube-collagen fiber for tendon repair; and carbon nanotube-collagen fiber coupled with neuron progenitor cells (NPCs) for neural regeneration; transdermal delivery, and disinfectant testing. Dr. Cheng is a study director on several regulated projects which require either Good Laboratory Practices (GLP) or FDA-compliant ISO 13485 medical device quality assurance compliance.
