Associate Professor of Statistics

Research Interests: My main research interest lies in the development of statistical methodologies for models with intractable likelihood functions or for misspecified models. These methodologies bring ideas from mathematical statistics (e.g. good old exponential families), machine learning (e.g. deep generative models) and physics (e.g. scoring rules probabilistic predictions) together through neural exponential models, generalised likelihood-free Bayesian inference etc. Developed methodologies can be applied in diverse fields e.g., meteorology and climate science, population genetics, epidemiology, computational biology and engineering sciences.
