Bristol University has been rated in a magazine poll as the fifth best research institution to work at outside the USA.
More than 3,500 post-doctoral researchers worldwide responded to the survey in The Scientist.
It concluded that access to resources and a good mentoring relationship rated highly among the priorities.
The only other UK institution in the top 14 was Cardiff University, which came 12th.
Sweden's Umea Science Center Plant was first in the poll.
Christian Carter, personnel manager at Bristol University, said: "This is a really great achievement and reflects the importance to the university of its research staff.
"There is, however, much work still to do and we have ambitious plans over the next few years to continue to keep Bristol 'employer of choice' for the very best researchers."
