Find our Sentientist Conversation here on the Sentientism YouTube and here on the Sentientism Podcast.

Katie is a theoretical cosmologist who holds the Hawking Chair in Cosmology and Science Communication at Perimeter Institute. Her academic research investigates dark matter, vacuum decay and the epoch of reionisation. Katie is also a popular science communicator who participates in social media and regularly writes for Scientific American, Slate, Sky & Telescope, Time and Cosmos. She is the author of the book “The End of Everything (Astrophysically Speaking)

Katie is vegan and has a sentiocentric moral scope. She has a naturalistic worldview, saying here: “I had a lot of trouble believing in anything that I didn’t have strong evidence for. It comes back to the scientific view point maybe. I didn’t have religious experiences. I didn’t have a feeling of connection with the divine. I wanted that feeling of connection … I found the practice very meaningful, but I never got the faith.”
