Just to throw this out there...
I'm a second year I/O PhD student at the University of Akron, and I have nothing but wonderful things to say about the program. We have faculty spanning a huge variety of expertise areas, the culture and people are wonderful, the funding is excellent, and both research and applied opportunities are plentiful.
It is a competitive program to get in to, but it is definitely worth applying!
Feel free to drop me a line if you have any questions or need advice about the application process- aecarr10(at)gmail.com.
