During May 20-31 2019 I will participate in a workshop on higher recursion theory and set theory. The conference will be held at the Institute for Mathematical Sciences, National University of Singapore.

As part of the conference, I will give an invited talk
entitled ** Turing degrees of hyperjumps**. My slides are
available in several formats:
PDF,
