Wallace, Joseph

About this team member

Joseph is a professor at Indiana University-Purdue University Indianapolis (IUPUI). He graduated from Georgia Tech with a BSE in Aerospace Engineering in 2002 before pursuing an MSE and Ph.D. in Biomedical Engineering from the University of Michigan. His Ph.D. work focused on mechanical and genetic influences on bone structure and function.

During his first year in the group, Joseph’s research focused on quantitatively assessing the internalization and trafficking of polycationic polymer-DNA polyplexes in cells. In September of 2008, he began working under an independent NIH/NRSA F32 Award. This grant is focused on understanding changes that occur in the collagen ultrastructure of bone (as well as dentin and tendon) in mice with the disease Osteogenesis Imperfecta (OI). Using Atomic Force Microscopy (AFM), high resolution imaging of Type I collagen is yielding a wealth of knowledge on how morphological aspects of the tissue ultrastructure contribute to the gross phenotype of mice with OI. Future studies are aimed at developing methods to mechanically probe collagen fibrils as well as extending these methods to larger animal models.
