Thanks to Sid for suggesting this and USC prompting me to get back in to the "Immigrant of the Day" groove.

Dr. Khorana is an 85 year old Indian born American who won the Nobel in medicine in 1968 for his work in genetic code interpretation. He has worked at various universities in India, the UK and Canada, but has called the US his home since 1960. Since his arrival in the US, he has really become one of the fathers of DNA research and many of his discoveries helped paved the way for modern genetic science.
