Tessa Baker

Royal Society University Research Fellow, Reader in Cosmology, Queen Mary University of London
I'm a cosmologist who works on understanding the role of gravity in our universe. In particular, I develop tools to test ideas about modified gravity and dark energy models with gravitational waves, large-scale structure and cosmological voids.

I completed my PhD at the University of Oxford, on devising mathematical frameworks for testing alternatives to General Relativity. I remained in Oxford for a five-year postdoctoral research fellowship at All Souls College, one year of which I spent as Fulbright Visiting Scholar at the University of Pennsylvania. In January 2019 I moved to QMUL to join the Cosmology & Relativity group as a Royal Society University Research Fellow and proleptic Reader.

I'm a member of the LIGO Scientific Consortium, DESC -- the consortium behind the Large Synoptic Survey Telescope (LSST) -- the ESA Euclid satellite, and the Laser Interferometer Space Antenna (LISA).
