Delhi-based Balachandran said he was feeling "proud and happy", describing Harris as a fighter.
Balachandran said that he would encourage Kamala Harris like any other parent and advice her to continue the good work.
Gopalan Balachandran, Harris' maternal uncle, said she will script many firsts if she wins and expressed the hope her top-level position will give Indians in the US "greater access" in interacting with the US administration.
