As a child, I always knew I wanted to be a physician. I found my passion for child neurology during my last years of medical school in Saint Petersburg, Russia. After immigrating to the United States, I continued training in child neurology, finally joining the Neurology Department at Boston Children's Hospital in 1998. I always had an interest in genetic and hereditary disorders, but later developed a special interest in mitochondrial diseases. The complexity and variability of these disorders presents a challenge, but it is also an exciting field with many innovative studies currently underway. As Director of the Mitochondrial Program, I apply the latest techniques to help our patients and their families manage their disorders. One of my top concerns is improving the quality of life for patients through the study and development of new drugs and therapies. My interest in neurometabolic and neurodegenerative disorders led me to develop a joint Neurometabolic Program with the Division of Metabolism. We see patients with undiagnosed and very rare disorders who have struggled to learn more about their conditions. New diagnostic methods allow us to provide answers for many of these families, as well as genetic counseling and special or experimental treatments.
