Fields Notes, Winter/Spring 2019 Fields_Notes_19.1 | Page 3

MESSAGE FROM THE DIRECTOR We entered 2019 with the prospect of new exciting programs and events, but overshadowed by the sad news of the passing, on January 18, of our friend, colleague, and recent Fields Institute Director, Walter L. Craig. We will remember Walter for his unflagging support of the Fields Institute, his good humour, and his kindness. The Fields Institute looks back on a busy fall 2018, highlighted by the major thematic program on Teichmüller Theory and its Connections to Geometry, Topology and Dynamics (July-December 2018), and the 2018 Fields Medal Symposium in honour of Maryam Mirzakhani. Later this year we will host the 2019 Fields Medal Symposium to celebrate the profound contributions of Artur Avila to chaos theory and dynamical systems. As we move through 2019, an ambitious and ground-breaking Thematic Program is underway here at the Institute: The Fields CQAM Interdisciplinary Thematic Program is bringing together people from industry and academic fields to work on problems across a wide range of disciplines, including history, art conservation, economics, health research, pharmaceutical manufacturing, machine learning, energy and mining, and financial analytics. The Program is well aligned with the Fields CQAM vision of making "Ontario the international leader in the development and deployment of advanced mathematical methodologies for the emerging knowledge economy". Another notable recent event was the Symposium on 50 Years of Complexity Theory: A Celebration of the Work of Stephen Cook (May 6-9, 2019). This four-day symposium featured an outstanding program of leading computer scientists, including many Turing Award and Nevanlinna Prize winners, centered around foundational research pioneered by Professor Stephen Cook (University of Toronto) on NP-Completeness and complexity theory. We extend our congratulations to Taboka Prince Chalebgwa, 2019 recipient of the Fields- AIMS-Perimeter Africa Postdoctoral Fellowship. We look forward to welcoming him to the Institute in July 2019 to begin his fellowship. My term as Director at Fields will end on June 30. I would like to express my warm thanks and personal appreciation to Arvind Gupta (Board Chair) and Deputy Directors Matheus Grasselli and Huaxiong Huang, who devoted so much of their talents and energy to Fields for the benefit of the whole community. In addition, I would like to thank all the staff at Fields over these past four years. Their hard work, dedication and flexibility have been essential in supporting the growing range and intensity of scientific activities at the Institute. The Fields Institute recently announced the appointment of Professor Kumar Murty (University of Toronto) as Fields Institute Director, starting July 1, 2019. Professor Murty’s scientific accomplishments, track record of international collaborations and extensive administrative experience will all be great assets for the Fields Institute in the coming years. We are also very grateful to Professor Tom Salisbury (York University), who has agreed to help our transition as Interim Deputy Director from July 1, 2019 to June 30, 2020. Ian Hambleton Director 1
