David H. Lyth

Professor David Lyth (21 June 1940) is a researcher in particle cosmology at the University of Lancaster. He has published over 165 papers as well as two books on early universe cosmology and cosmological inflation.^[1]

He is noted for his work in the area of inflation model building and the observational consequences of models of inflation. In 1997, he discovered the Lyth bound which relates the tensor-scalar ratio of perturbations in the CMB to the variation of the inflaton field during inflation.^{[2] [3]} He proposed the Curvaton Scenario in 2001, with David Wands of Portsmouth University.^[1] He was awarded the Fred Hoyle Medal and Prize in 2012.
