I got 4 mates finishing up their Ph.D in nanotechnology this year, done some interesting research!
2 of them have secured research positions within the uni, getting paid decent (approx 55k) Not sure if they are doing any lecturing.. But i think it is something like $100/hr for lecturing and $75/hr for tutorials? Pretty good
1 x 3hr lecture everyday and you'd be cheering
They have kinda talked me into going back and doing my PhD, which i'm going to commence in 2011.
Really, do something that you will enjoy doing, that is my best advice. I started off doing software engineering thinking it would be a good salary, i quit after a year cuz i hated it, switched to nanotechnology, enjoyed it, completed it, did teaching, enjoyed it, completed it, now teaching and doing a post grad business degree to expand my horzions and then doing my PhD in nanotechnology in 2011.
I'd also look into doing a combined Business and Science degree, just having that business experience could help you move up the ladder quicker i reckon
