With an Indian company, you can fund phd research through the prime ministers fund (they pay the remainder of the fees and support). I think it is a wonderful program. Assume funding a top PhD student might be $20k per year.

If I had the gumption and ready money, I would just reach out to university deans with a letter indicating an intent to fund a particular profile. It might help to have a professor in the USA to help with the mentoring, because some of the academic connections may be valuable.

But this particular topic has potential because the tech could be cutting edge — so you can contribute to a field that has been very staid.
