The University of Arizona is a top tier research institution.
Pros: vast resources available for research purposes, flexible schedule.
Cons: poor pay, and long hours.
The University of Arizona is a great place to conduct research. I was afforded the opportunity to complete my master's degree in geology. Due to the extensive funding provided by my advisors I was able to focus on research and class work, without having to TA classes. This allowed me to graduate in two years.
