I am a team player, and I approach treating patients and building the Neurosurgery Department's capabilities from a collaborative, multidisciplinary perspective. 

As the interim chief of the Department of Neurosurgery, I am passionate about harnessing the tremendous resources of Boston Children's Hospital to make our care truly patient centered. Through my leadership, I have brought together representatives from many departments to create new options for our patients, including forming the Brain Injury Center and a clinic for treating incontinence due to spinal cord malfunction.

I am an athlete and enjoy team sports; I rowed for Dartmouth College and have played competitive rugby and squash. I work with Sports Medicine to treat children with sports-related injuries and I co-direct the premier national concussion meeting, the HMS Neurological Sports Injuries conference.

A rotation through the neurosurgical suite at Georgetown University Medical Center as a resident gave me an early taste for the field and why it might suit me. The brain translates into everything about who we are, and there is so much that doctors still don't know, which creates exciting new opportunities. I came to the realization that I wanted to work with children when I led groups of kids on bike trips during the summers between medical school. I love treating children because of their resilience and capacity for recovery.

My research efforts document the ground-breaking clinical advances I have achieved as a leader of cross-functional treatment teams that are changing care locally and nationally.

In craniofacial surgery, we have developed and documented multiple novel approaches.  We have pioneered the use of particulate skull autograph to fill in cranial defects, markedly reducing the dependence on allografts and allowing for normal skull development. Our work with this has been ongoing for a decade, with both clinical and research components. This has been published for both primary and secondary skull defects, and currently its usage is being expanded internationally.

I am one of the leading surgeons internationally performing minimally invasive endoscopic correction of craniosynostosis. Many aspects of this work have been published, including the marked effect endoscopic surgery has on ocular disorders in coronal synostosis. My work with anesthesiologists and the Craniofacial team validating the efficacy of transexamic acid in craniosyntosis surgery helped established a new standard of care that reduces bleeding in craniosynostosis surgery.

In spinal surgery, orthopedic surgeons and I have published the largest series of modern spinal instrumentation for the cervical spine in children, defining its use for surgeons across the country and setting the standard of care. We have developed a posterior lateral trans-pedicular approach for correction of congenital spinal deformity in children with hemivertebrae, changing the correction from two surgeries to a single procedure. Many surgeons have now adopted this technique, although many consider it too technically challenging and we are therefore referred patients nationally and internationally.

We see over 400 concussion patients each month in the Sports Medicine and Neurology clinics, and I have published the world’s largest surgical series on herniated disks in the pediatric population, identifying several new concepts, including its marked predilection for female athletes.

We have also described a novel approach to dermoid tumors at the skull base, involving removal of the nasal bones to achieve complete resection of the lesion with almost no risk of recurrence. Together with colleagues, I have described the use of intraoperative bone scan for the resection of spinal osteoid osteoma. I have published the largest series on the surgical treatment of intrasacral meningoceles, standardizing the indications for surgery and type of surgical repair.

My clinical work has led to many publications that are defining new standards of care. These include:

Professional History

I specialize in the treatment of pediatric craniofacial abnormalities, spinal disorders, sports-related injuries and trauma to the brain and spine. As interim chief of Boston Children's Hospital's Department of Neurosurgery, I believe in fostering a collaborative, multidisciplinary approach, and delivering to patients the best possible experiences and outcomes.

My commitment to improving healthcare is reflected the depth and breadth of my education. After an undergraduate degree in French from Dartmouth College, I studied medicine at Columbia University, ultimately concluding my training as a fellow in pediatric neurosurgery at Boston Children's Hospital. I honed my skills as a manager and executive through Harvard Business School's Program for Leadership Development.

I am committed to improving the lives of patients with craniofacial abnormalities, spinal disorders and brain injury. I specialize in endoscopic, or minimally invasive, approaches to neurosurgery. I work closely with Sports Medicine to maintain an active practice in sports-related injuries. I advocate for brain injury awareness beyond Boston Children's Hospital, and am a member of the board of directors of ThinkFirst, the leading national brain and spinal cord injury prevention foundation.

In 2012, I was elected to lead the Physician’s Organization at Children’s Hospital, the umbrella group that directs contracting, billing, benefits and employment issues for over 1,000 doctors. I assumed the presidency in 2014, and have lead a great deal of change. I have been responsible for instituting a shared service center to centralize professional billing, a move that I hope will improve the experiences of families being treated at our hospital.

I have also created several new collaborations between subspecialties at Boston Children's Hospital to deliver care to patients whose needs were previously unmet. I worked with providers from the departments of Gastroenterology, Urology and General Surgery to address incontinence associated with spinal problems. I direct and helped to create the Brain Injury Center, a previously unavailable resource that harnesses the expertise of our Neurosurgery, Trauma Surgery, Neurology, Neurophysiology and Psychiatry departments. We have formed a center for complex pediatric cervical spine problems along with orthopedics, and our multidisciplinary Craniofacial Center remains one of the foremost in the nation.

One of the most extensive collaborative efforts I have participated in has been the development of the unique intra-operative MRI at Boston Children's Hospital, a project for which I facilitated partnership between the hospital administration, anesthesia, radiology, and engineering. This effort has resulted in great clinical success; I moderated a webcast highlighting the technology in a live brain surgery, which received a national “Webby” award.
