Despite being relatively small, my department has three faculty in finite combinatorics, in addition to having me in logic. I recently gave a series of two talks in our seminar to present a broad overview of classical computability theory, and to present some more recent applications to mathematics, via Reverse Mathematics and via Weihrauch Reducibility.
