I think this is his issue. I had the same problem with Devry. If E-commerce dried out he is not longer offered courses at University of Phoenix . He must look for approval for different courses so he can teach more areas. By the way, I would stay away from PhDs with very narrow IT specializations such as E-commerce, Information Security, etc. E-commerce courses are not longer in demand so if you have a PhD in E-commerce, you would need to take more courses to teach something else (Two of the Universities that I teach closed down E-commerce programs). It is better to get a PhD a generic IT field such as Information Systems or Computer Science since you can qualify to teach more courses with little extra work.
