Research Interests
My research is concerned with the musculoskeletal system. We have
special interests in the bioelectrical properties of bone and connective
tissue; the electrical stimulation of bone growth and fracture healing;
electrokinetic effects in bone; biomaterials, hydroxyapatite, and
implants; and fluid flow effects on bone cells and their relationship
to bone tissue engineering. We also do research on tissue engineering
of bone graft material in rotating bioreactors. We have introduced
new technologies for 3-D scaffolds in bone tissue engineering that
facilitates earlier matrix synthesis and calcification. These technologies
combined with the use of rotating bioreactors offers the opportunity
to advance this field to the point of clinical trials.
