I'm hoping there are some business PhD students out there who can speak to this. I am 50, and am looking at returning to school to earn my PhD in I.T. or similar field. I have an MBA from Penn State, class of '88. I have 20+ years of experience in high tech, including senior/exec management roles, and a lot of start up experience. I was told back in my MBA days that I had PhD potential but I was too intent on making my MBA bucks at the time. Now I would like to reinvent myself, focus on research and teaching, and make a difference in the world of business. I understand that half or less of PhD candidates complete their program and dissertation, and it would be interesting to know why. I am not stuck on a top tier school, but would prefer a program that shares my interests, has professors that I can relate to and share interests with, and will allow me the freedom and support to explore my passions. I have found that "second best" organizations often try much harder, have better stipends, and more research opportunities. Fortunately, in Central Texas, I have a lot of options without moving. Comments? Opinions? My kids think this is a great idea, the spouse...not so much.
