Our department is large and diverse, with roughly 70 professors and teaching assistants, and we cover many major fields of mathematics, such as complex analysis, global analysis, functional analysis, algebra, topology, numerical mathematics, graph theory, combinatorics, theoretical computer science, mechanics, financial mathematics, probability and statistics. We pride ourselves on being not just good mathematicians, but also friendly and accommodating to our students. Mathematics is hard enough as it is!

The department also organizes 11 weekly research seminars and a monthly colloquium.
