PhD Princeton University, 1986

Robert Myers (PhD Princeton University, 1986) is the Director and BMO Financial Group Isaac Newton Chair at Perimeter Institute. A native of Deep River, Ontario, he joined Perimeter as a founding faculty member in 2001, was its Scientific Director from 2007 to 2008, served as Faculty Chair from 2011 to 2018, and became Director in 2019. Prior to coming to Perimeter, he was a professor of physics at McGill University. Myers’ research focuses on foundational questions in quantum theory and gravity. His contributions span a broad range, including quantum field theory, gravitational physics, black holes, and cosmology. Several of his discoveries, such as the “Myers effect” and “linear dilaton cosmology” have been influential in seeding new lines of research. His current research focuses on the interplay of quantum entanglement and spacetime geometry and on applying new tools from quantum information science to the study of quantum gravity.

Among his honours, Myers has been awarded the Herzberg Medal by the Canadian Association of Physicists (1999), the CAP-CRM Prize in Theoretical and Mathematical Physics by the Canadian Association of Physicists and the Centre de Recherches Mathématiques (2005), the Vogt Medal by the Canadian Association of Physicists and TRIUMF (2012), the Queen Elizabeth II Diamond Jubilee Medal (2013), and the Distinguished Alumni Award from the University of Waterloo (2018). In 2006, he was elected a fellow of the Royal Society of Canada. Myers has been recognized as one of the world’s most influential scientists, appearing on the Thomson Reuters/Clarivate Analytics list of “Highly Cited Researchers,” five times. He has been a member of the Canadian Institute for Advanced Research in the Cosmology and Gravity program (1998-2017) and an associate member in the Gravity and the Extreme Universe program (2017-present). He has served on numerous advisory boards, including the Banff International Research Station (2001-05), the Kavli Institute for Theoretical Physics (2012-16), the William I. Fine Theoretical Physics Institute (2015-19), and the Max Planck Institute for Gravitational Physics (2018-present).

Myers remains active in both teaching and supervising graduate students through his cross-appointment as an adjunct professor in the Department of Physics and Astronomy at the University of Waterloo. He has supervised and co-supervised over 150 postdoctoral fellows, PhD students, and master’s students over his career, roughly 50 of whom now hold faculty positions around the world, including at Princeton, Cambridge, and Oxford.

PhD École Normale Supérieure de Lyon, 1994

Laurent Freidel (PhD École Normale Supérieure de Lyon, 1994) joined Perimeter Institute first as a visitor in 2002 and then as faculty in 2006. He served as Faculty Chair from 2021 to June 2023.

PhD Stanford University, 2008

Asimina Arvanitaki (PhD Stanford University, 2008) is the Stavros Niarchos Foundation Aristarchus Chair in Theoretical Physics at Perimeter Institute, where she has been a faculty member since 2014. She previously held research positions at the Lawrence Berkeley National Laboratory at the University of California, Berkeley (2008-11) and the Stanford Institute for Theoretical Physics at Stanford University (2011-14). Arvanitaki is a particle physicist who specializes in designing new experiments to test fundamental theories beyond the Standard Model. These experiments rely on the latest developments in metrology, such as atomic clocks and the optical trapping and cooling of macroscopic objects. She recently pioneered a new experiment that can look for new spin-dependent forces in nature at an unprecedented level of precision. Arvanitaki has also shown how astrophysical black holes can diagnose the presence of new particles through the process of black hole superradiance, giving signatures that can appear in LIGO or any future gravitational wave telescope. She was co-awarded the 2017 New Horizons in Physics Prize by the Breakthrough Prize Foundation and, in 2022, was awarded the CAP-TRIUMF Vogt Medal.

PhD Princeton University, 2006

Latham Boyle (PhD Princeton University, 2006) joined the Institute’s faculty in 2010. From 2006 to 2009, he held a Canadian Institute for Theoretical Astrophysics Postdoctoral Fellowship and was a junior fellow of the Canadian Institute for Advanced Research. In recent years, Boyle’s research interests have spanned a number of topics in cosmology, fundamental physics, and mathematical physics. In cosmology, he recently proposed and has been developing (with Neil Turok) a new cosmological model in which the big bang is a kind of mirror and the universe before the bang is the CPT mirror image of the universe after the bang. This line of thought leads to rigid new explanations for a number of observed features of our universe (including its homogeneity, isotropy, and flatness; the arrow of time; dark matter; and several properties of the primordial perturbations, along with a clue to why the cosmological constant is so mysteriously small). In fundamental physics, he recently pointed out an intriguing new connection between certain patterns in the Standard Model of particle physics and the structure of a remarkable mathematical object called the exceptional Jordan algebra. With Kendrick Smith, he introduced “choreographic crystals,” which are new types of “crystals” in which the basic elements perform a choreographed dance that can have much higher symmetry than any instantaneous snapshot reveals. With Paul Steinhardt, he found all “Penrose-like tilings” (cousins of the famous Penrose tiling) in all dimensions. With Madeline Dickens and Felix Flicker, he discovered that the regular tessellations of hyperbolic space (which play a central role in the burgeoning field of “discrete holography”) induce self-similar quasiperiodic tilings (like the Penrose tiling) at the boundary of hyperbolic space and pointed out their importance for discrete holography.

He was also one of the 347 members of the Event Horizon Telescope collaboration to win the 2020 Breakthrough Prize in Fundamental Physics. He has been elected as a fellow of the Royal Society of Canada, announced in September 2022, for his outstanding scientific achievements.

PhD University of Oxford, 1999

Will Percival (PhD University of Oxford, 1999) is jointly appointed at the University of Waterloo, where he holds the Mike and Ophelia Lazaridis Distinguished Research Chair in Astrophysics, and is the Director of the Waterloo Centre for Astrophysics.
