I have read some nanotechnology experts' CV's and found that many of them also come from engineering backgrounds.
Maybe you can shed some light on another alternative, can someone get a Master's in physics or chemistry with a BS in business?
Actually it's shorter and doesn't include English and elective courses.
I know it's strange. Have you ever heard of Dr. Klaus Schwab? He's the founder of the World Economic Forum. He has a Master's in Public Administration, a PhD in Mechanical Engineering, and another PhD in Economics. So, I'm guessing it can be done.
