Charles Dumoulin, PhD, received his BS in chemistry from Florida State University in 1977 and his PhD degree in analytical chemistry in 1981. He then spent three years performing high-resolution NMR spectroscopy research at Syracuse University before moving to General Electric’s Research and Development Center in Niskayuna, NY, where he became part of the team that developed the first industrial prototype MR scanners.
Later, Dr. Dumoulin made major contributions to the fields of magnetic resonance angiography (MRA), dynamic MRI and interventional MRI (resulting in over 100 issued patents). In 2008 Dr. Dumoulin moved to Cincinnati and became the scientific director of the Imaging Research Center. His current research interests include MRI imaging of neonates, MR-guided focused ultrasound ablation, and interventional MR.

In 2000, Kim M. Cecil, PhD, Antonius deGrauw, MD, PhD, and Gajja Salomons, PhD, discovered creatine transporter deficiency syndrome, a genetic disorder caused by mutations in the creatine transporter gene (SLC6A8). Male patients demonstrate a significant reduction or absence of creatine in the brain, as indicated by MR spectroscopy. This is an X-linked mental retardation disorder thought to be second only to fragile X in prevalence.

Director, Research in Patient Services
Director, Reading and Literacy Discovery Center
Advanced neuroimaging applications of MRI in pediatrics; functional MRI of language, hearing and neuroplasticity following brain injury; brain development.
Scott Holland is a physicist by training with a BS (1980) in physics from Muhlenberg College, Allentown, PA, and an MS (1982) and PhD (1985) in engineering and applied science from Yale University.
After a year (1985-86) as a research engineer with the Electromagnetic Sciences Laboratory at Stanford Research Institute (SRI International), Menlo Park, CA, Scott returned to the Yale School of Medicine as a post-doctoral fellow (1986-88) and later as an assistant professor (1988-94) of diagnostic radiology.
He joined the faculty of the University of Cincinnati College of Medicine in 1994 as associate professor of radiology and pediatrics and served as scientific director of the Imaging Research Center at Children's Hospital Medical Center until 2003.
In 2005 he founded the Pediatric Neuroimaging Research Consortium with the Department of Pediatric Radiology and the Divisions of Neurosurgery, Neurology, Psychiatry and Biostatistics at Cincinnati Children's. The PNRC continues to grow and currently consists of eight full-time faculty members engaged in research using a broad range of neuroimaging techniques to study the developing brain under the influence of diseases of childhood. From 2009 to 2013, Scott led the Communication Sciences Research Center as its founding director. Currently he is serving as director of the new Division of Research in Patient Services.
His research currently focuses on pediatric neuroimaging applications of MRI, MEG and EEG methods; including perfusion MRI, functional MRI, and image processing methods, to study development of the neural circuitry of hearing, language, speech and reading capabilities through childhood. His discoveries regarding changes in brain activity and connectivity during typical childhood development and under the influence of neurological disorders have been influential in our understanding of neuroplasticity and reorganization of the developing brain in response to injury.

John Racadio, MD, has been practicing interventional radiology (IR) for 14 years and has been the division chief of interventional radiology at Cincinnati Children’s Hospital Medical Center for the past 11 years. He has expertise in performing a wide range of vascular procedures including angiography, angioplasty, embolization, vascular access, and thrombolysis in patients ranging from 500g to 150kg.
He is also the director of the interventional radiology research lab, which is part of the Department of Radiology Imaging Research Center (IRC). This state-of-the-art IR lab, which is identical to our clinical IR labs, possesses cutting edge digital flat detector technology including 3-D rotational angiography (3DRA), 3-D Roadmapping, and C-arm cone beam CT. These features provide superior image quality for digital subtraction angiography, 3-D angiography reconstruction, and “CT-like” imaging. Lab support staff includes RT(R) licensed IR technologists, and an IR lab manager. The long term goal of the IR research lab is to develop new image guided interventional procedures and imaging techniques and protocols to improve clinical outcomes. Having an IR research lab identical to our IR clinical labs facilitates translation of lab results into clinical practice.

As a postdoctoral fellow at University of Michigan and University of Rochester, Dr. Vannest was trained to use functional MRI to study the brain mechanisms underlying language skill.
Dr. Vannest came to Cincinnati Children's Hospital Medical Center in 2006, and her current research makes use of functional MRI to examine how epilepsy and neurodevelopmental disorders affect language function, ultimately leading to better treatment and educational strategies for children with these disorders.

Jason C. Woods, PhD Director, Center for Pulmonary Imaging Research
is an imaging scientist who focuses on basic and translational pulmonary MRI and CT. His lab studies new methods for in-vivo assessment of regional pulmonary function, microstructure and physiology using hyperpolarized gases (3He and 129Xe) and 1H MRI, in addition to multi-volume CT. As new therapeutics for pulmonary diseases are developed, these new methods will be used for efficacy assessment and potential image guidance.
Director, Center for Pulmonary Imaging Research
Hyperpolarized gas; pulmonary MRI; translational studies; image-guided pulmonary interventions
Dr. Woods is one of the world’s leading experts on hyperpolarized-gas MRI and the use of such gas MRI to measure regional lung function, microstructure and physiology. He began his career at Washington University, where he helped lead multiple team projects related to lung imaging, biology and physiology. Interests in both world-class science and higher education led him to pursue simultaneous roles as a professor and academic dean, when he became program director for Washington University’s MARC (T34) training program.
Currently Dr. Woods directs the Center for Pulmonary Imaging Research at Cincinnati Children’s Hospital Medical Center. The center is a multidisciplinary research and training program at the intersection of pulmonary medicine and radiology.
