Fields Notes Summer/Fall 2019 2 | Page 3

DIRECTOR'S MESSAGE I am delighted to be writing my first Fields Notes message as Director of the Fields Institute. This issue focuses on the exceptional activity at Fields over the last few months including an exciting new partnership with the National Research Council of Canada (NRC), and highlights from the many lectures, seminars, workshops, and symposia. First, I must gratefully acknowledge the impressive efforts and lasting impact of Ian Hambleton and Huaxiong Huang during their tenure as Fields Institute Director and Deputy Director, respectively. Under their leadership, Fields welcomed world-class mathematicians, launched major partnerships that had been years in the making, and experienced significant growth. I am grateful for their improvements and vision, and I look forward to carrying this momentum forward. In May, we marked half a century of complexity theory with a symposium honouring the great Stephen Cook, including talks by leading computational complexity researchers, a round-table student lunch, and a banquet to celebrate Cook’s phenomenal career. An ambitious six-month Interdisciplinary Thematic Program by Fields CQAM was completed in June. The program provided applied research and advanced training opportunities for students and industry professionals. Over 1200 participants attended collaborative and problem-solving workshops, courses, seminars, and special lectures on various topics, including public health, economics, digital humanities, and social sciences. The program activity included a machine learning graduate course, with a very special lecture by 2019 Turing Award winner Geoffrey Hinton. In June, Fields also welcomed the Honourable Kirsty Duncan, Minister of Science and Sport, to officially launch the NRC-Fields Mathematical Sciences Collaboration Centre, a joint partnership between the NRC and the Fields Institute. The centre, which will be housed at Fields, will establish conditions for applied mathematics to flourish. This partnership exemplifies our focus on collaboration: activities will include opportunities for training, publication, patent development, and commercialization of technology between both organizations. As the year progresses, we continue along this trajectory of exciting activity at Fields. In November, the Institute hosts the 2019 Fields Medal Symposium, honouring the work of Artur Avila, and the Thematic Program on Homological Algebra of Mirror Symmetry. Also in November, the Focus Program on Data Science and Optimization brings together data scientists and optimization scientists and bridges these fields. The slate of ongoing workshops, conferences, and special lectures continue to keep the Fields Institute humming with activity. I truly look forward to my term as Director of Fields, and am grateful for the support of everyone who engages with the Institute, particularly of Interim Deputy Director Tom Salisbury and Board Chair Arvind Gupta.
