My research interests encompass magnetic resonance imaging (MRI), biomedical engineering and physics. My goals include bringing MRI into the neonatal intensive care unit (NICU) and developing innovative image-guided therapies. I have been an active researcher in magnetic resonance (MR) for more than 40 years and have worked at Cincinnati Children's since 2008.
I have made several significant contributions to the field, including the following innovations:
Most of my publications have been in the field of MR. While many of my abstracts, papers and patents have had a widespread impact in research and clinical practice, several of these report innovations that are the first in their class. The following is a brief descriptive summary of these works.
During my career, it's been my honor to receive several awards and appointments, including:
I am an author or co-author on 134 peer-reviewed articles, 28 book chapters and over 281 conference proceedings. I have given 221 invited lectures. I also have 117 issued US patents with an additional 11 patents pending. My H-index is 63 (including publications and patents).
