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.

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
Congratulations to Samaneh on her publication in Acta Biomaterialia (Impact Factor 10.6), titled "Biaxial mechanical properties of the bronchial tree: Characterization of elasticity, extensibility, and energetics, including the effect of strain rate and preconditioning."
Congratulations to Talyah on her first manuscript, coauthored by Katie, Samaneh, and Crystal in Physiological Reports titled "Associating local strains to global pressure–volume mouse lung mechanics using digital image correlation ." By quantifying strain evolutionary behavior in relation to pressure–volume measures, we associate time-continuous local to global mouse lung mechanics for the first time and further examine the role of volume and rate dependency. Research was conducted in collaboration with the Nordgren Lab (Colorado State University)
The non-confidential disclosure of our new device for pulmonary function testing in the 21st century (also published as a PCT patent application) is now available through the Office of Technologies Partnerships at UCR.

Congratulations Crystal, Samaneh, Katie, and Talyah on their article in Respiratory Research "Examining lung mechanical strains as influenced by breathing volumes and rates using experimental digital image correlation." In the age of COVID-19, the insights provided by the real-time continuous measures, and the kinetics to kinematics pulmonary linkage established by this experimental study offers valuable characterizations for computational models and establishes a framework for future studies to compare healthy and diseased lung mechanics to further consider alternatives for effective ventilation strategies.
