Project Description: Vibration damping by structural materials is a critical requirement for creating a comfortable consumer experience and for protecting everything from soldiers to bridges. In particular, we need stiff, strong, lightweight materials that also dissipate energy effectively through viscoelastic deformation, but current materials are largely an either/or compromise between load bearing and vibration damping.

Project: Endothelial Mechano-Biology Research
Professor: Eno Ebong
Project Description: We seek to define endothelial cell and glycocalyx mechanisms of blood vessel regulation by solid-fluid mechanics. The project tests the hypothesis that fluid (blood) and solid (blood vessel wall) forces cooperate to regulate endothelial cell behavior via the glycocalyx, a sugar complex that is anchored to and coats endothelial cells and can convert fluid and solid force stimuli into cellular responses. Endothelial cells lie at the vascular fluid-tissue interface and play an essential role in maintaining blood vessel health. An incomplete knowledge of endothelial cell mechanobiology mechanisms results in limited vascular disease prevention and treatment efficacy. This project will address this critical knowledge gap.
Learning Objectives: (1) Characterize glycocalyx architecture; (2) Link glycocalyx structure to cell molecular mechanisms; (3) Clarify how molecular stimuli evoke an endothelial cell response that impacts production of nitric oxide, a vasodilator.
Role of REU Student: (1) design and conduct rigorous research in the areas of bioengineering and endothelial mechanobiology: (2) collect and access relevant data; (3) create written and oral presentations of study results.
Expected Learning Outcomes: (1) apply interdisciplinary fields to research; (2) design of experiments and data interpretation; (3) responsible and ethical conduct of research; (4) technical communication.
