Research Interests
Will Handley is a Theoretical Cosmologist, studying the very earliest moments of the universe. He completed his PhD in 2016 under his supervisors Anthony Lasenby and Mike Hobson.
His main interest is in "Initial Conditions for Inflation", examining the effect that high energy physics has on the universe a split second after the Big Bang. In 2014, he proved that that the preinflationary universe takes an extremely generic form, independent of the type of particle which drives the early accelerated expansion of the universe.
In addition to theoretical investigation, he also examines the observational consequences of these new ideas; testing theories against the latest data from microwave telescopes using the University supercomputers.
Recently, his work has focussed on developing novel Bayesian algorithms for highdimensional parameter estimation and model comparison using nested sampling. Possible applications currently under investigation include protein folding and compressed sensing, in addition to cosmological parameter estimation and model comparison.
Will Handley is a member of the Planck Core HFI team 2.
