Dr. Andrew Tolley

Biography

Andrew Tolley is a theoretical physicist focused on gravitational physics and theoretical cosmology. His research involves quantum effective field theories, which have become a dominant modern tool in theoretical physics, especially concerning embedded possible UV completion scenarios. He has worked on developing theoretical models concerning the early universe, inflation, non-Gaussianities, and cosmological perturbations, as well as braneworld models and extra dimensions related to Galileon theories. Much of his work addresses explanations for the late-time acceleration of the universe, focusing on Dark Energy and Modified Gravity, notably Massive Gravity, to tackle challenges like the Cosmological Constant Problem. He has also led work on the S-matrix bootstrap and Positivity Bounds, exploring the landscape versus swampland in String Theory. Currently, he serves as the Programme Director for the Quantum Fields and Fundamental Forces MSc program at Imperial College London and is a co-author of the 450-page book "Modified Gravity", part of the Encyclopedia of Cosmology, published by World Scientific. Over his career, he has achieved several awards, including the Royal Society Wolfson Research Merit Award and has been a visiting fellow at the Perimeter Institute for Theoretical Physics.
