Dr Giorgos Vasdekis

I am a Research Fellow, working with Dr. Richard Everitt on likelihood-free inference problems, using ABC techniques.

Academic Background:

I received my PhD from the University of Warwick in 2021. Before that, I finished my B.Sc. in Mathematics at the University of Athens in 2015 and I received a MASt from the University of Cambridge in 2016.

Research Interests:

I am generally interested in Markov Chain Monte Carlo (MCMC) techniques and their applications in Bayesian Statistics. Currently, I am working on using gradient methods to generate more efficient Approximate Bayesian Computation (ABC) algorithms. I am also working on model misspecification problems. At the same time, I am very interested in using Piecewise Deterministic Markov Processes for MCMC.
