In case the uni offers you support or scholarship, the name of that sponsor should be on the form who will pay your air tickets and part of your tuition. If everything is paid by university then list your parents as sponsor for air tickets, monthly allowances , personal expenses. Never include the name of your professor as sponsor. And make sure you include a detailed letter with the official support letter from university. You still need to show funds for trivial expenses like sanitary, food, emergency funds etc.
