John Power's 60th Birthday!

We are delighted to host a workshop in honour of John Power on the occasion of his 60th birthday at RIMS, Kyoto University. John, recently retired and now a honorary professor at Macquarie University, Sydney, is staying in Kyoto as a visiting professor of RIMS for the winter of 2019/2020. During his stay in Kyoto, John turns 60.

As described in the webpage of the Bath workshop for John held in June, John has made substantial contributions in category theory and its applications to computer science throughout his career. At the same time, he has been a wonderful teacher, mentor and friend to many of us, with his exceptional insights, kindness, and humour.

Since the 1990's John has regularly visited Japan and worked with Japanese researchers, including several PhD students and young postdocs. John's presence has made great impact on Japanese research community of semantics of computation and related fields; John has co-authored a number of papers with young Japanese researchers and served as their mentor.

This workshop will feature talks by John's friends and collaborators as well as young Japanese researchers who are under the influence of John's work in a broad sense.
