On April 30 and May 1, 2012 the department was visited by an external review team of four distinguished mathematicians and statisticians. Academic departments are typically reviewed every seven years or so, and this was our year. The team assessed our strengths and weaknesses and made recommendations to the department and administration. Overall, the review was favorable. The summary says the following: "The committee was pleasantly surprised and excited to find such a vibrant and generally young department on a definite upward trajectory, more than responsibly fulfilling its role within the university."
