Tessa Baker is a cosmologist and gravitational wave astronomer at Queen Mary University of London (QMUL). Her research centres on the laws of gravity and their role in shaping our universe. To put new ideas about gravity to the test, she works with experiments both on the ground and in space, such as the Vera C. Rubin Observatory, the LIGO-Virgo-KAGRA gravitational wave detectors, and the LISA satellite mission. She is a Royal Society University Research Fellow and Reader at QMUL. Baker completed her training at the University of Oxford. She spent periods living and working in Philadelphia, Boston, New York and Sydney before moving to start her research group at QMUL in 2019. When not studying the cosmos, she likes to test gravity by hiking up significant things. She lives in south London with too many houseplants. -- A very special thank you to our Patreon supporters who help make these videos happen, especially: modsiw, Anton Ragin, Edward Unthank, Robert L Winer, Andy Carpenter, William Hudson Don McLaughlin, efkinel lo, Martin Paull, Ben Wynne-Simmons, Ivo Danihelka, Kevin Winoto, Jonathan Killin, Stephan Giersche, William Billy Robillard, Jeffrey Schweitzer, Frances Dunne, jonas.app, Tim Karr, Alan Latteri, David Crowner, Matt Townsend, THOMAS N TAMADA, Andrew McGhee, Paul Brown, David Schick, Dave Ostler, Osian Gwyn Williams, David Lindo, Roger Baker, Rebecca Pan -- The Ri is on Patreon: https://www.patreon.com/TheRoyalInstitution and Twitter: http://twitter.com/ri_science and Facebook: http://www.facebook.com/royalinstitution and TikTok: https://www.tiktok.com/@ri_science Listen to the Ri podcast: https://anchor.fm/ri-science-podcast Our editorial policy: https://www.rigb.org/editing-ri-talks-and-moderating-comments Subscribe for the latest science videos: http://bit.ly/RiNewsletter Product links on this page may be affiliate links which means it won't cost you any extra but we may earn a small commission if you decide to purchase through the link. |
