I grew up in Salt Lake City, Utah, educated by my father, an engineer, and my mother, a nurse.

The wide-open vistas of my youth -- with mountains and canyons outside my doorstep -- and the pioneer spirit of the western settlers have had profound influences on my approach to care and research. I believe in taking my time to talk to patients and charting an individual direction in medicine.

I bring a strong interest in engineering, computer programming and mathematics to my practice. An early influence in these areas came during a summer of high school, when I was an intern in the lab of Ed Catmull, then a graduate student at the University of Utah who subsequently founded Pixar, the technology company that changed art, animation and entertainment forever. Thinking about how to approach animation as a computational problem (we were trying to digitize pictures to create a 3D representation of a moving person), I had a chance to think about how cutting-edge computational techniques might dramatically change a field -- and that is something I have tried to bring to neurosurgery.

That interest carries through to today. I hold nine U.S. patents and am interested in creating devices to help my patients. I study epilepsy from a mathematical perspective, using equations to predict specific places in the brain where seizures originate and designing surgeries that can cure them. I teach residents how to bring math, engineering and science to bear on a clinical problem, and stress that thinking this way will lead to better work on every case they undertake.


I am a pediatric neurosurgeon with a strong interest in innovative approaches to the dynamic brain maladies of children, especially epilepsy and hydrocephalus. My clinical efforts are closely tied to my research program, the Neurodynamics Laboratory.

I received my medical degree in 1981 from a joint program poised uniquely at the intersection between engineering and medicine, the Harvard-MIT Program in Health, Science and Technology. I hold the Webster Family Chair in Neurosurgery and Neuroengineering at Boston Children's Hospital, direct the hospital's Epilepsy Surgery Program and am an associate professor at Harvard Medical School. My work is multidisciplinary and focused on applying engineering and mathematical approaches to my practice.

I have brought several innovations to clinical practice. These include a new technique to monitor shunt flow in patients with hydrocephalus, including the use of cardiac-gated MRI scans, thermal detection of shunt flow, and a valve massager technology. I have also developed a new technique to predict seizure focus using intracranial data gathered from implanted electrodes, which will one day allow surgeons like myself to better plan epilepsy surgeries. My practice has grown in part because of successful patient approaches developed during planning of such research programs.

I also have a strong interest in improving pediatric neurosurgery and epilepsy surgery abroad, specifically in China. In that context, I have been an adjunct professor in functional neurosurgery at Xuanwu Hospital, affiliated with Capitol Medical University, Bejing Institute of Functional Neurosurgery. I have been specifically working on a mechanism to review surgical cases in real time with colleagues at Beijing's Children's Hospital.

This clinician offers Virtual Visits (video consultation)s for follow-up care in clinically-appropriate cases.
