Taking the Oath. I was naturalized as a United States citizen in Philadelphia today. This was a big step for me personally that started with my move to the US more than a decade ago. As an immigrant physician-scientist, I have lived through the most dynamic decade in child neurology, which is my chosen field of work. During this time, many previously unnamed conditions have been deciphered, genetically characterized, and moved towards targeted treatments such as gene therapies. With this as a background, let me summarize why I am excited to be a US citizen.
