Dr. Jack Jewson


Current Position:

I am currently working as a Postdoctoral Assistant at the Barcelona School of Economics (BSE), Universitat Pompeu Fabra (UPF), working with Dr. David Rossell and Dr. Piotr Zweirnik.

Form 1st March 2022 I will start a 2 year Juan de la Cierva Postdoctoral Fellowship.


I obtained my PhD titled ''Bayesian Inference in the M-open world'' from the University of Warwick (in collaboration with the University of Oxford) as part of the Oxford-Warwick Statistics Programme (OxWaSP) under the supervision of Prof. Jim Q. Smith (Warwick) and Prof. Chris Holmes (Oxford) (Submitted 2019, Awarded 2020).

Research Interests:

My research interests surround the methodological and philosophical challenges encountered when conducting Bayesian analyses for modern, high dimensional inference problems. In such scenarios a 'full' Bayesian analysis is inevitably impossible and one must resort to approximations, either at a modelling or a computational level.

I am particularly interested in general Bayesian updating and the use of loss functions to make principled Bayesian inference and improved decision making.

Other interests:

  • Model misspecification, robust statistics and the M-open world

  • Divergences, loss functions and scoring rules

  • Variational inference

  • Differential privacy
