Xiaodu Wang, Ph.D.

Professor

ASME and AIMBE Fellow

Department of Mechanical Engineering, UTSA

Currently seeking M.S. students

My research interests lie in the area of mechanics of biological materials and structures, including ultrastructural origins of bone fragility fractures, digital model of trabecular bone and its application in deep learning prediction of bone fractures, and prediction/prevention of bone fragility fractures. I have been serving as PI for multiple NIH (R03, R21s and R01s) and NSF supported projects.

Related Diseases: Osteoporosis, osteopenia, osteogenesis imperfecta and diabetes

Techniques: MicroCT, synchrotron X-ray scattering, light and confocal microscopy, FTIR, Raman spectroscopy, SEM, TEM, AFM, NMR/MRI, DXA, HPLC and Mechanical testing
