I am in the USA, admitted to thesis based graduate degree (PhD), but my supervisor has no research paper experience in the area on the research he wants me to do. He did his PhD in something related, then for the last 20 years worked in other areas, and is now coming back to the area of his PhD degree. I am in Electrical Engineering.
Is this advisable to do this? Is this a red flag? Is this like working with a company that is working outside their core competence?
His research is sponsored by companies who will mentor me in these areas as they are paying for the research costs.
