I'm about to start my graduate life and was wondering if anyone has any experience being a college professor. I know the obvious, publish papers, be good at research, etc... I have no idea how to publish a paper right now, but hopefully I'll learn that in grad school. I noticed that there is extremely tough competition between college professors (my field is engineering), which I didn't expect at all. I thought it would be a nice calm, peaceful job, but I guess I was wrong. One thing that I really wanted to know is if I can become a professor in a field other than my PhD. Say I have a MS in Mechanical Engineering and a PhD in Stochastic Systems (from an Industrial Engineering department). Can I become a professor in Mechanical Engineering if I show some competence in the area? What if I have a MS in Mechanical Engineering, MS in finance, and a PhD in Stochastic Systems? Can I become a professor in finance (again, if I show competence in that area)? If the answer is yes, what constitutes "showing competence" in an area?
