Personal Statement

After having earned my Ph.D. in Neuroscience, I became fascinated by the intricacies and processes of the central nervous system, and the role a neurosurgeon plays in tracing them. I realized that neurosurgeons are responsible for far more than surgical intervention. We play a critical role in getting our patients back to living normal lives, with healthy brain function. That's why I went on to earn an M.D. degree as well. 

I consider it an honor to treat patients with brain tumors and cerebrovascular disorders. The challenges are immense, but I get the daily satisfaction of helping patients get back to the families, and their lives.
