Sunnysujan, Your research topic sounds interesting. Good luck with your PhD Xfer. I am in a completely different field than yours. I am in the USA now and working here. I don't think you know me though. However, you should have seen me. I have been to your house a couple of times. I know your brother very well. I don't have contact with him though. If you get chance, say my hello to him. Talk to you later.
