How is life as a PhD research scientist/staff scientist in academia? I am a PhD student in genetic epidemiology. When I started my PhD, I was certain I wanted to be a professor - three years into my degree, I am seriously rethinking that choice.

There are parts of my work now as a grad student that I love -- reading articles, putting what I’ve learned together to design studies, doing the analysis, writing code... I am aware of job titles like "research scientist" and "staff scientist" that sound like they might get to spend more time on these things than professors do, but I have some questions about how this works.

(These questions refer to positions in academia or similar settings like NIH intramural - I know industry is very different so I won't try to cram that into the same question!)


When/why do people hire research scientists/staff scientists instead of postdocs, and how do the positions differ from being a postdoc?
How is job stability? By this I don’t mean job security, so much as “How often do people end up having to find a new job?” “How easy/hard is it to find a new job when that happens?” and “Can you usually find a new job at the same university/in the same city?”
How is geographic flexibility? Would I still have to be willing to move anywhere in the country like I would if I were looking for a tenure-track job, or would I be able to choose where I wanted to live and then look for jobs there?
Do people in these positions first-author papers?
You do get paid more than a postdoc... right?
In my experience there are two types of staff scientists.

The first are people who go out and get their own grants. Basically, if an institution thinks you have a legitimate shot at acquiring funding, they will give you access to their grants office to allow you to submit a grant to cover your salary and lab space. If you are good enough to bring in your own funding, life is good. You can live/work wherever you want and more or less name your own salary (of course you need to bring in the grants to cover the salary). As your salary is tied to your grant(s), there is a lot of stress associated with going down this road. A six month funding gap can be disastrous.

The second are people who work on the grant of someone else. This puts you at the same risks of having a funding gap, but know you are not responsible for getting the money, but someone else it. It requires a good working relationship with the PI as they have to be able to justify why paying more for a staff scientist is needed. It terms of flexibility/security, if the PI loses funding, leaves, or retires, getting another job can be really difficult and you should not expect to really have choices in where you will end up. Often grant funding, especially NIH funding, needs to be planned 18+ months out. People just don't have unallocated chunks of funding large enough to cover a staff scientist.
