I am a retired professor from North Carolina. Presently I am a teacher of physics and calculus in one of the private schools in Charlotte, NC. I travel to Chennai once a year where my mother, and sisters live. I grew up in Chennai one of the top localities and after a degree from the Loyola college and an engineering degree from IIT Benaras Hindu University studied in Tokyo University, Duke University and later at the University of California at Berkeley. My wife Jessica has traveled to almost all places in India; and one of our children is now works for Microsoft in India and another is a faculty in NC State University. Email me if you need advice but I may be a bit slow. [email protected]
