2.  Developed multiple novel animal models for heterotopic ossification after trauma and used
them to study the cellular and molecular mechanism of this pathological bone formation.
Rotator cuff muscle research program:
 Established a research program of cellular and molecular mechanism of rotator cuff muscle
atrophy, fibrosis and fatty infiltration after massive tendon ruptures using clinical and
preclinical specimen.
 Developed various mammal animal models (from mouse to sheep) of rotator cuff tear ruptures
and repairs.
 Discovered the role of muscle residential fibro-adipogenic progenitor cells (FAPs) in rotator
cuff muscle pathology.
 Studied the epigenetic regulation of directed differentiation of FAPs in vitro and in vivo.
Neuro-musculoskeletal trauma research program:
 Evaluated novel diagnosis and treatment methods for compartment syndrome with FDA
approved Licox issue oxygenation probe in a canine model.
 Used biomimic nanofiber to treat segmental peripheral nerve injury repair in a rat model.
 Tested the role of FDA approved pulsed electromagnetic field (PEMF) therapy in muscle
regeneration.
 Explored the role of a novel intracellular isoform of matrix metalloproteinase-2 (MMP-2) in
muscle degradation after ischemia-reperfusion injury.
 Developed a novel anti-MMP-2 antibody in treating spinal cord injury and tested it in a
preclinical mouse model.
 Evaluated the role of brown/white fat in muscle regeneration.
Teaching and mentoring duties:
 260 teaching hours/year (100 hours teaching, 160 hours mentoring).
 Mentored 5 postdoc, 5 medical students, 10+ research associates and 10+ volunteers.
 Setup and manage a biomedical research lab with 5 lab members for the past 8 years.
UNIVERSITY OF CALIFORNIA AT SAN FRANCISCO – San Francisco, California 2/2006 -9/2008
Assistant Research Biologist, Department of Orthopedic Surgery
Stem cell research program:
 Developed inducible immortalized mesenchymal stem cell lines for musculoskeletal repairs.
 Studied the interaction of muscle residential mesenchymal progenitor cell and satellite cells
during muscle regeneration.
 Evaluate endothelial linage stem cells in muscle degradation and regeneration.
BAYLOR COLLEGE OF MEDICINE – Houston, Texas
Postdoctoral Associate, Department of Orthopedic Surgery 12/2001 to 2/2006
Directly measured nano-structure and mechanical properties of articular cartilage damage in
rheumatoid and osteoarthritis. Evaluated the combined effect of estrogen and mechanical loading
on anterior cruciate ligament (ACL) fibroblast gene expression. Investigated gender difference of
collagen gene expression in teen athletes with ACL injuries.
