Hi, I have BSc and MSc degree in physics (writing my thesis currently), and I have decided to change career and become an Industrial Engineer instead. Specifically I am fascinated by Operations Research. I am thinking to get an undergraduate degree and then PhD in IE. Does anyone have a suggestion? My MSc thesis is about Classical General Relativity. I think I have an overall good Mathematics knowledge, but I dont have any experience with computer simulations and numerical calculations. Is getting a second undergraduate degree stupid?
