@oristarA,
To clarify the typo (bank instead of rank) of the thread's title:
Here is the actual article addressed in the thread.
Quote:Jeremy Berg: An Independent Scientist Departs NIH's Ranks

a number of persons forming a separate class in a social hierarchy or in any graded body.
So when Jeremy Berg departed from the National Institute of Health's ranks, he quit his job as director of the $2 billion National Institute of General Medical Sciences. So
ranks here refer to his fellow scientists working alongside him while he held the leadership position in that particular branch of the NIH.
