- Research Statement:
- Professor Jasiuk develops research-based models to explain the structure and behavior of man-made and biological materials. Her work with man-made materials aims at understanding why the properties of composites made with nano-sized particles differ from those made with micro-sized particles. She is particularly interested in the interface that surrounds such particles and comes into contact with the surrounding material, and how this interface contributes to the shape, size and boundary conditions of composites as a whole.
Her work with biological materials focuses on bone. One ongoing project aims to explain the underlying mechanism that causes osteoporotic bone to break. Using electromicroscopy, Professor Jasiuk has successfully characterized the physical structure of normal bone and osteoporotic bone at both the micro- and nanoscales. After finding no significant structural differences between normal and diseased bone at either scale, she has redirected her efforts to identify chemical and mechanical differences in these two bone types that might lead to the development of non-invasive techniques that can be used within a clinical setting to characterize and compare the chemical structure of normal and osteoporotic bone.
Two projects with other researchers also involve bone. Professor Jasiuk and Jo Ann Cameron, associate professor of cell and developmental biology at the Institute for Genomic Biology, are using frogs as a model to study limb regeneration. Frogs make a good model, because tadpoles regenerate lost limbs on their own while mature frogs do not. Yet, if an adult frog is missing a large piece of bone, implanting a synthetic scaffold will encourage the natural bone to grow back. Professors Jasiuk and Cameron are trying to identify the chemical and mechanical stimuli that are involved in both types of regeneration and to determine what, if any, differences there are between such stimuli in young frogs versus older frogs.
Professor Jasiuk has also teamed up with John Dantzig, a fellow professor in the Department of Mechanical Science and Engineering, to study the effects of solid and fluid phases of bone on bone remodeling. Together, the two professors are investigating how bone remodeling is influenced by mechanical and biological stimuli and how these stimuli influence the properties of the resulting bone. Their work may one day shed light on the changes in bone that occur due to implants and osteoporosis.
