Talks

I generally prefer giving blackboard talks, but sometimes slides are simply better suited. Here is a list of selected talks and slides (in pseudorandom order…).

• Blackboard talk given in March 2023 for a Cosmology Group Meeting at the Perimeter Institute presenting work to appear on past singularities and extensions in inflation (the work in question is now online; see arXiv:2305.01676): video
  I also presented this topic as part of the Copernicus Webinar and Colloquium Series in July 2023: slides

• Talk given during the 2024 Canadian Association of Physicists Congress presenting arXiv:2405.11016: slides
  I gave a longer version of this talk also at the Institute for Basic Science in Daejeon, Korea, as part of a Workshop on Cosmological Collider: slides

• Online talk given during the 2021 Canadian Association of Physicists Congress mainly presenting arXiv:2012.04911, arXiv:2102.05550, and work to appear: slides
  I gave a longer version of this talk also at McGill on 01/12/2021 and at Perimeter on 30/11/2021: slides and video

• Online talk given during the Atlantic General Relativity Conference on 19/05/2022 mainly about my paper on complex metrics in cosmology: slides

• Online talk given during the conference Alternative Gravities and Fundamental Cosmology on 06/09/2021 mainly about my paper on the principle of finite amplitudes in cosmology: slides
  I gave a close version of this talk also during an online workshop on 08/11/2021 organized by the Yukawa Institute for Theoretical Physics (Kyoto University), Recent Progress of Quantum Cosmology.

• Online talk given at the Fields Institute to mathematicians on 21/07/2022 as part of the Low Regularity Physics and Geometry Seminar about the stability of modified gravity from the point of view of effective field theory: slides
  See also the presentation on YouTube below.

• At the Fields Institute on 05/10/2022, I also gave a talk to mathematicians as part of the Workshop on Mathematical Relativity, Scalar Curvature and Synthetic Lorentzian Geometry about theories of modified gravity with limited curvature: slides
  See also the presentation on YouTube below.

• I also presented the previous topic during the online workshop Physics of the Early Universe - An Online Precursor (organized by the International Centre for Theoretical Sciences) on 01/09/2020 about my papers on limiting curvature (mainly arXiv:1911.06040 and arXiv:2005.10844): slides
  See also the presentation on YouTube below.

• Online talk given for the Copernicus Webinar and Colloquium Series on 25/10/2021 mainly about my paper on viscosity and anisotropies (but also briefly talking about arXiv:1711.10472): slides
