Does stating multiple degrees from a single university on a CV disadvantage an applicant for a research or lecturing position? I have a bit of a potentially unusual situation with my CV.  Over the years while I worked in an unrelated field (to pay the bills etc), I completed multiple degrees - all degrees were completed to a good standard.  The degrees are either in education (earlier ones) or physics (later ones).

However, most of the degrees are from a single university - including the final few, which were in closely related fields. All culminating in a PhD.

My question is - is there any disadvantage to having multiple degrees listed from the same university on a CV when applying for a postdoc or lecturing position?
No, there is no disadvantage to having multiple degrees from the same university.  Normally you should not leave any degrees out of your CV.  There are advantages to having experience at multiple universities, but that does not have to be in the form of a degree.
