Does changing department affect my rank? I am a PhD graduate from department of CS. I might get an offer to join as an assistant professor at a different department (industrial design) to work in a multidisciplinary project. My question is that if I change my department or even my institution in future would it affect my rank? Will my researching effort being counted in future?
EDIT
I need to clarify that after the end of my contract, I will be evaluated to be promoted as an associated professor. My question is that since I might work for industrial department, the rank given to me would be valid if I join, say, CS department?
When you receive your job offer, it will offer you a specific position/rank. It would be unusual to offer someone a lower rank than they already have, but not inconceivable when moving between universities (i.e. moving from Northern State University to Harvard). It would be very unusual for a department within your university to offer you in effect a demotion.
You would always have the choice to not accept.
