We investigate the interplay between tissue mechanics and damage/remodeling. This includes examining the effects of acute bone loading on bone remodeling using PET-MRI and studying how altered cartilage loading affects cartilage microstructural health in osteoarthritis via quantitative MRI.

An example project (left) combines finite element modeling with PET-MR to examine how bone strains relate to changes in metabolic activity after exercise.
