I had my BSc in Physics, MSc and PhD in Energy System Engineering. I worked as a assistant lecturer and a lecturer for three years teaching different maths courses, statistics and Physics. I had to move from where I was lecturing before because of my family and now I am in search of a Lecturing or Post-Doc opportunity. Most of the job adverts I see are more specific on a particular field. I am beginning to wonder if my diversification is a disadvantage.
Also, if there is a post-doc or lecturing opportunity at your university, I won't mind applying.
