Hmmm.... What's your GPA and academic achievements?
Honestly after my luck, I quickly realized that despite tons of research experience in undergrad, my marks turned off every grad school I applied to. No one gave a dog's left testicle that I did research a year and a half.
Anyways, bitterness aside, I believe the University of Iowa is the one of the best in the US. If you do some searching around, you can find grad school ranking websites that let you rank by your preferences. Purdue is good... Colorado state isn't bad either. Also, many Canadian universities have good master's programs.
