Biomechanics and Mechanobiology

Biomechanics and Mechanobiology

Biomechanics and Mechanobiology involves the study of how physical forces and the mechanical environment interact with living systems in health and disease at multiple scales: molecular, cellular, tissue/organ-level, organism-level.

We now know that cells and tissues are exquisitely sensitive to their mechanical environment and to mechanical stimulation, a fact that is important in many physiological and pathophysiological processes. For these reasons, biomechanics and mechanobiology interface synergistically with many other focus areas. For example, devices implanted in the body must be designed so that they are mechanically “tuned” to tissues they comes in contact with, so as to avoid initiating an undesirable cellular response. Similarly, biomaterials function best when they mechanically match their target environment.

Mechanics is central to human movement and the understanding of motor control. This is relevant in a diverse number of applications, ranging from physical human-robot interactions to injury biomechanics to neurologic movement disorders

At the cellular level, differentiation of stem cells, and migration, apoptosis and division of many cell types depends on their mechanical environment. The growth and function of axons depends on mechanical processes. Aberrant mechanical signaling underlies important diseases such as atherosclerosis, heart failure, osteoarthritis and glaucoma.

At Georgia Tech and Emory, we have built on our outstanding pedigree in this area to create one of the largest and most dynamic biomechanics groups in the world. In addition to using mechanics in designing medical device and engineered tissues, we study, inter alia, the molecular mechanics of cellular adhesion and signaling in the immune system, the hematologic system, and in cancer; the function of the lymphatic system in health and disease; how blood flow interacts with heart valves, and how to design better replacement valves; how mechanics can trigger arterial disease and homeostatic tissue growth; the role of mechanics in the eye, particularly in glaucoma; how altered mechanics play a role in pulmonary disease; and mechanical triggers for cell death in the central nervous system.
