The bioMechanics Experimental and Computational Health Lab
Welcome to bMECH
The bMECH lab sits at the interface of medicine and engineering. Led by Professor Mona Eskandari, Ph.D., our biomechanics research utilizes mechanical theory, experimental characterization, and computational modeling to explore the multiscale and adaptive response of biological systems. We focus on investigating pulmonary function through an engineering lens, seeking solutions to scientific questions surrounding lung disease. We aim to enable and develop predictive technologies and optimize innovative strategies for medical intervention.

We were demonstrate how fibrotic lungs may be particularly susceptible to damage when contrasted to the strain patterns of healthy counterparts, helping to advance understanding of how ventilator induced lung injury develops.
Prof. Eskandari's invited Letter to the Editor was published in the American Journal of Respiratory and Critical Care Medicine theorizing that the fundamental mechanical differences observed between artificial ventilation and physiological breathing can be explained using the thick-walled derivation of the Lamé equations.
Congratulations to Katie and Samaneh for receiving the Graduate Research Mentorship Program and Dissertation Year Program Fellowships !
Congratulations to joint first co-authors Samaneh and Crystal on publishing recent groundbreaking scientific findings in the prestigious American Journal of Respiratory and Critical Care Medicine (Impact Factor 30.5). In order to mitigate ventilator injury, we address a long-standing debate in the pulmonary medical community: do ventilator breathing mechanics mimic that of natural breathing? Using an innovative multi-apparatus interface developed in our lab, we minimized confounding factors by subjecting the same lung specimen to both loading modes. We found exclusive evidence that both global and local energetics, stretches, and distortions are reduced in physiological breathing compared to artificial ventilation. This also holds implications for the COVID-19 Pandemic. News Feature
