Every summer, we invite up to two eminent statisticians/probabilists to teach a short special topic course to our Ph.D. students. These 1-2 week-long courses, allow our Ph.D. students to engage with an eminent researcher to learn and discuss advanced topics in a relaxed setting. Recent Summer Visitors include Peter Buhlmann, John Lafferty, Sourav Chatterjee, Minge Xie, Denis Talay, Liza Levina, and Roman Vershynin.
