KEYNOTE SPEAKER

Injury thresholds - it takes the whole biomechanics toolbox

Abstract

fiogf49gjkf0d
Cells within the body routinely tolerate deformations during activities such as head turning and breathing, yet when cells are deformed beyond a safe limit or injury threshold, function and structure are altered temporarily or even permanently. Our goal is to determine functional and structural injury thresholds in the brain and lung, and use them to understand mechanisms of traumatic brain and lung injury. In addition, the lab's study of the biochemical and molecular biology of injured cells facilitates the development of preventive and therapeutic measures. Because human tissues tend to be inhomogeneous, anisotropic and nonlinear, and the tissues of interest undergo large strains, determining the complex relationship between cellular and macroscopic responses requires an integrated biomechanics approach consisting of several simultaneous rigorous engineering experimental and theoretical analyses. Tissue mechanical properties and injury thresholds are measured and used to develop computational models. These models are used to generalize our experimental cell and tissue findings and determine macroscopic injury mechanisms and injury thresholds. These studies parallel clinical investigations regarding the treatment and detection of traumatic injury.
