Professional Interests

The long-range goal of the Ebong Mechanobiology Lab is to identify mechanically regulated cellular and molecular targets to prevent, diagnose, and treat diseases associated with vasculature. I have been integrating chemical and biomedical engineering, molecular biology approaches, and in vitro and in vivo experimentation to study cellular and molecular mechanisms of cardiovascular function over a range of combined fluid-solid mechanical stimuli. I have been particularly focused on the endothelial cells that line the blood vessel wall and are in direct contact with both fluid (blood) and solid (blood vessel wall) forces that are both part of the natural mechanical environment of blood vessels. These cells detect these forces, and, in response, guide blood vessel function to maintain health. My molecular focus has been on the vasculoprotective glycocalyx that coats the endothelial cells, and on defining its structure, chemical composition, and mechanotransduction activities. Diseases associated with the vasculature are thought to occur as consequences of endothelial glycocalyx shedding.

I look forward to advancing the endothelial glycocalyx research to study its role in endothelial cell pathophysiological remodeling and function in mechanical conditions associated with vascular health and atherosclerosis, cancer metastasis, and brain and neurovascular health as well as mild traumatic brain injury. Towards this end, my research group has a number of productive collaborations that are ongoing with vascular pathologists, oncologists, neuroscientists and other experts. Successful outcomes of our collaborative research, to date, include technical publications in peer-reviewed journals. I anticipate that the findings of our work will someday be applied to the engineering and commercialization of novel tools for targeting the blood vessels, endothelial cells, and/or glycocalyx to diagnose and treat multiple diseases that are associated with vascular dysfunction.

Successful outcomes of my work, to date, include strong technical publications, award recognition, and funding from NIH NHLBI, NSF CMMI, and industry partners.

Training opportunities are available for students interested in both basic and clinical research.
