Rajulama,

The main reasons of denial was

(1) Low citations records

(2) I did not discover anything different that could change the thinking of scientific community

(3) I was not the lead figure of the NIH funded projects even though I had important roles

First time I included 8 reference letters from top scientists (4 from inner cricle and 4 from out circle)

RFE submission (7 letters from out circle)
