Miss Hann was editor of the university's student newspaper
Former Tomorrow's World presenter Judith Hann is to be awarded an honorary degree from Durham University.
Miss Hann, who hosted the former BBC science show for 20 years, will receive the honorary title of doctor of civil law at a ceremony later.
The 67-year-old graduated in zoology at the university in 1964 before becoming a broadcaster and science writer.
She has advised ministers on GM crops and hosted international conferences since leaving the show in 1994.
Miss Hann said: "I spent some of the happiest years of my life in the North East and met some of my very best friends at university.
"Durham has always been the special place for me, the birthplace of my first son, Jake, and the home of my father and his family."
The honorary degree will be awarded at Durham Cathedral by the university's chancellor, author Bill Bryson.
