Antonio Padilla

Antonio Padilla (born 1975), also known as Tony Padilla, is a British theoretical physicist and science populariser. He is Professor of Physics at the University of Nottingham, where he is also associate director of the Nottingham Centre of Gravity.

Early life and education Padilla studied at Cambridge University as an undergraduate, and completed his PhD at Durham University in 2002. At Durham he was part of the Centre for Particle Theory, a research group with members in both the Department of Mathematical Sciences and Department of Physics.

Career Padilla held research positions at the University of Oxford and the University of Barcelona before joining the University of Nottingham.

In 2016, he and collaborator Nemanja Kaloper of the University of California, Davis received the Buchalter Cosmology Prize for their work on the cosmological constant problem. This produced a 'relatively small cosmological constant', but also predicted that universe expansion will eventually reverse direction. The book was developed from a series of public lectures delivered by Padilla to raise money for a friend to receive cancer treatment abroad. Topics covered include the theory of Graham's number.
