As a pediatric neurosurgeon, I’m trained to deliver both open and endovascular (minimally invasive) approaches for curing vascular disorders of the brain and spinal cord in children. I am also trained in interventional radiology. I was inspired to pursue my career by the shortage of information and the controversy in caring for children with vascular disorders and stroke of the brain and spinal cord.

I’m the director of the Pediatric Cerebrovascular Disease and Stroke Center at Cincinnati Children’s. We have a strong history in multidisciplinary pediatric care at every visit. I also serve as a physician scientist attempting to create an innovative patient-specific treatment in the basic science research lab and translate these cutting-edge discoveries in a safe, effective manner for childhood care solutions.

I was chosen as one of Cincinnati Business Courier’s top Forty Under 40 in surgical innovation.

My research focuses on overcoming identifiable genes responsible for abnormal brain vessel development and increased stroke risk. We also want to harness white-matter plasticity and neural stem cell regeneration.

In my free time, I enjoy jazz drumming.
