Participants at the Workshop on Dynamics and Moduli Spaces of Translation Surfaces • October 22 - 26, 2018 About 100 participants, primarily early career mathematicians, attended the summer school. The Workshop on Geometry of Teichmüller Space occurred the week after the summer school, on August 27-31. This workshop featured 19 speakers who gave talks across a broad range, spanning much of Teichmüller theory and connected areas. There were over 90 participants in total and many spectacular talks on cutting edge research in higher Teichmüller theory. Some of the talks gave new insights into the intricate geometry of Teichmüller and moduli spaces and the coarse geometry of mapping class groups. The workshop also included a lunch-hour round-table discussion on women in mathematics, which was attended by almost all workshop participants. The Workshop on Dynamics and Moduli Spaces of Translation Surfaces, held on October 22- 26, had roughly 70 registrants. This workshop brought together participants in the broad area of translation surfaces, which has been influenced from areas across dynamics, geometry, and even algebra and number theory. There were 20 speakers who talked about work across dynamical, geometric, and algebro-geometric perspectives. The workshop also benefitted from some speakers talking about related topics like random Riemann surfaces, dynamics on infinite volume homogeneous spaces and stability conditions in more general settings. The main body of the program featured three graduate courses and two regular seminars. The three courses reflected the diversity and breadth of the Thematic Program. The first course, Topology and Geometry of Automorphism Groups of Free 8 Groups, was taught by the Dean’s Distinguished Visiting Professor, Mladen Bestvina (University of Utah). The second, Dynamics and its Connections to Teichmüller Theory, was taught by Jon Chaika (University of Utah). Finally, the course on Geometry and Dynamics in Teichmüller Space Equipped with the Thurston Metric was taught by Kasra Rafi (University of Toronto). Courses were well attended by local students, postdocs, and long- and short‑term visitors. The seminars ran weekly and one was organized by the Program's postdoctoral fellows. The Coxeter lectures had 35 participants and featured three inspiring lectures by Curtis McMullen (Harvard University). These lectures were titled Planes in Number Theory, A Panorama of Teichmüller Curves; and Billiards and the Arithmetic of Non-arithmetic Groups. The program was fortunate to overlap with the Fields Medal Symposium in honor of the late Maryam Mirzakhani (Fields Medal 2014). The symposium had roughly 140 participants and featured 16 talks. The Public Opening featured remarks by Ian Hambleton (Fields Institute Director), Vivek Goel (Vice President, Research and Innovation, University of Toronto), Donna Strickland (2018 Physics Nobel Prize winner and Professor, University of Waterloo), and Carlos Kenig (President- Elect, International Mathematical Union). Jenya Sapir (Binghamton University), Maryam's first student, delivered a moving introduction. The evening ended with a riveting public lecture
