Research Interests

I am interested in understanding the physical mechanisms behind bubble-enhanced ultrasound biotherapies and application of the acoustic signatures of insonified bubbles.  This creates a research program that spans acoustics, signal processing, imaging, and medicine. Two current foci of my work are passive acoustic mapping and acoustic droplet vaporization for the treatment of cardiovascular disease.

Summary

Kevin Haworth received a B.S. degree in physics from Truman State University in 2003 and M.S. and Ph.D. degrees in applied physics from the University of Michigan, Ann Arbor, MI, in 2006 and 2009, respectively.  Following his graduate studies he performed a postdoctoral fellowship at the University of Cincinnati.  As a fellow, he received a Ruth L Kirschstein National Research Service Award (F32) from the NIH National Heart, Lung, and Blood Institute to support his research. He is an Associate Professor in the Division of Cardiovascular Health and Disease within the Department Internal Medicine, College of Medicine at the University of Cincinnati.  He also maintains a secondary faculty appointment within the Department of Pediatrics and the Department of Biomedical Engineering, College of Engineering and Applied Science at the University of Cincinnati. Dr. Haworth teaches and is the Director of Data and Analytics for the College of Medicine’s Medical Sciences Baccalaureate Program. Additionally, he teaches at both the undergraduate and graduate level in the Department of Biomedical Engineering.  Dr. Haworth is a member of the IEEE, the International Society for Therapeutic Ultrasound (ISTU), the Acoustical Society of America (ASA), and the American Institute of Ultrasound in Medicine (AIUM).  He serves on the Bioeffects Committee and Technical Standards Committee, along with being the Secretary of the Basic Science and Instrumentation Community of practice at the AIUM. He is a member of the Biomedical Acoustic Technical Committee and Public Relations Committee for the ASA. He is a former Goldwater Scholar and is involved with the Barry M. Goldwater Scholarship and Excellence in Education Program at both the local and national level. 

Kevin Haworth’s research interests broadly include biomedical ultrasound imaging and therapy.  In particular, he is currently directing and conducting research in medical ultrasound including the use of bubbles for diagnostic and therapeutic applications. His work includes studies of cavitation imaging and acoustic droplet vaporization for gas scavenging and imaging. These studies have been funded through the National Institutes of Health, the American Heart Association, and institutional awards. Ongoing studies of passive cavitation imaging are being pursued to develop image-guidance for cavitation-based therapies such as drug delivery and histotripsy.  Additional studies are being performed to modify the imaging algorithm for improved image quality. Dr. Haworth is the principal investigator of an NIH-NHLBI R01 grant entitled "Ultrasound-mediated controlled hypoxemic reperfusion for inhibition of reperfusion injury.” While new therapies to restore blood flow during myocardial infarction (i.e., a heart attack) can be life-saving, up to half of the volume of heart tissue at risk during a heart attack dies, paradoxically, due to the return of blood flow. The previously oxygen-started heart muscle responds to the influx of oxygen by creating free radicals that damage the patient’s heart cells, so-called reperfusion injury.  This project uses a novel, ultrasound-mediated technique to sequester oxygen from the blood to limit free radical formation and reduce reperfusion injury.
