Current Position:
I am currently a Senior Lecturer in the Department of Econometrics and Business Statistics at Monash University in Australia
Previous Positions:
Mar 2022 - February 2024: Juan de la Cierva Research Fellow, Department of Economics and Business, Universitat Pompeu Fabra (UPF) working with Dr. David Rossell
Sept 2019 - Mar 2022: Postdoctoral Research Assistant, Barcelona School of Economics (BSE), Universitat Pompeu Fabra (UPF) working with Dr. David Rossell and Dr. Piotr Zweirnik.
Education:
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 Sept 2019, Awarded June 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
Variable selection and graphical modelling
Differential privacy
