Supervision
I welcome enquiries from prospective Ph.D. students who are interested in undertaking research in any of my areas of research interest.
My current Ph.D. students work on research topics relating to bootstrap inference under serial dependence, nonlinear regime-switching models, dynamic factor models, and machine learning methods.
