Biography and Research Information
OverviewAI-generated summary
Sam E. Stephens' research focuses on developing and utilizing advanced imaging and modeling techniques for cardiovascular applications. His work includes the creation of custom wall-less cardiovascular flow phantoms using tissue-mimicking gel for in vitro studies. Stephens has investigated high-resolution imaging of the mitral valve using 7 Tesla MRI and developed an in vitro mitral valve model with unrestricted ventricular access. He has also explored simulating nephron ion transport function and modeling peripheral arterial and venous pressure signals.
His research network includes collaborators such as Morten Ø. Jensen and Hanna Jensen from the University of Arkansas at Fayetteville, with whom he has co-authored numerous publications. Stephens' scholarship is reflected in his h-index of 6 and 26 total publications. His recent work also includes investigations into in vitro blood clot formation and dissolution for testing stroke-treatment devices, and the relationship between the sinotubular junction-to-aortic annulus ratio and supravalvar aortic stenosis severity.
