Én ezzel adnám vissza, angolul ezt jelenti:

"Distinguished professor" is a title sometimes given to the top tenured professors in a university, school, or department. Distinguished professors are usually awarded this title because they are highly regarded and seen as a leader in their field of study.

Distinguished Professor. This designation specifically recognizes extraordinary, internationally acknowledged scholarly attainment in an individual discipline or field. By nature of their appointment as Distinguished Professors, individuals are expected to make special contributions to the intellectual advancement of their home departments and schools, as well as to the institution as a whole.

Magyarul nem látok rá bevett formát, lehetne még "kiemelkedő szaktekintély", vagy "tekintélyes professzor" (ebben a cikkben összefoglaló cikkek rovatcímével kapcsolatban szerepel így: https://mnot.hu/wp-content/uploads/2019/10/321.pdf), de mint professzori cím, az angol meghatározások alapján nekem a kiemelten elismert tetszik a legjobban.
