About the Research

 

Advancing Low Field MRI for Point of Care Diagnostics through Engineered Systems for Quantitative Assessment of the Extra Cellular Matrix State of Soft Tissues

 

Our research will advance the adaptation of low-field magnetic resonance (MR) imaging (MRI) as a novel, non-invasive, and affordable point-of-care (POC) diagnostic imaging method capable of assessing the state of extracellular matrix components in connective tissues and quantitative tracking treatments of associated diseases (i.e., myofascial pain syndrome, osteoarthritis, etc.),  leading contributors to disabilities worldwide.

Research Projects

 

We combine a deep understanding of physics, materials science, and engineering approaches to examine complex biological systems. Students and researchers in the lab developed expertise in engineering fundamentals, materials fabrication, molecular motion, magnetic resonance methods/applications, polymer physics, 3D printing, data science, and instrument construction. 

Researchers are prepared to take an interdisciplinary approach to impact the advancement of noninvasive POC diagnostics, increasing access to affordable medical imaging, and improving researchers’ capability to connect physiological states with underlying tissue pathologies through low-field (LF) MRI.
