Sendhil Ramamurthy: US or UK raised?

I'm wondering how Sendhil Ramamurthy (one of the main characters on NBC's new hot series "Heroes" got to studying in London. This article says he was born in the US, but not if he was raised there. He went to drama school in London, UK, and seems to have (or act) a very English-y Indian accent. I cant seem to find any info that clarifies his growing up experience. Sendhil Ramamurthy is definitely an actor who is good at playing a non-stereotypical Indian (from India) character. He doesnt have a stereotypical accent, for starters. I wonder if any Heroes fans have answers.
