Professional info

My research is focused on the physical mechanisms involved in the control of tissue growth, healing, and homeostasis, especially bone adaptation and regeneration influenced by mechanical environment, as well as how these mechanisms can be utilized in the treatment and prevention of disease and injury and bone tissue engineering. It is clear that bone senses and responds to biomechanical stimuli towards the achievement and maintenance of a structurally appropriate skeletal structure. In addition to strain magnitude, bone tissue has the ability to differentiate between shear and normal strain, cycle number, loading frequency, and even fluid pressure and its gradients. The interdependent roles of these mechanical signals are investigated through empiric and analytic models to provide support for the complex interactive mechanism of bone remodeling.

My research is also focused on the development of non-invasive scanning acoustic diagnostic system for tissue quality, and therapeutic ultrasound. The goal of this project is to develop a new technology, which will lead to a better understanding of the progressive adaptation of bone loss in aging populations and microgravity environment. The technology will be used for assessing musculoskeletal complications such as osteoporosis and accelerate fracture healing.
