"Post-Postdoc" Independent Researcher with Office in University?
Many universities offer positions with titles such as "research professor" or "staff scientist" or other similar titles. These all indicate the same basic phenomenon: a researcher who is generally supported by "soft money" (In other words, a position subject to sufficient funding), but who is otherwise more or less "permanent" staff. Such scientists may or may not have their own dedicated office space, depending upon overall space constraints within the department and within their boss's research group.
