Academic Background :
I am a final year MASDOC student in University of Warwick. Before that, I finished my B.Sc. in Mathematics at the University of Athens in 2015 and I received a MASt from Homerton College, University of Cambridge in 2016.
Research Interests :
I am interested in Markov Chain Monte Carlo techniques and their applications in Bayesian Statistics. I am currently working with Prof. Gareth Roberts on using Piecewise Deterministic Markov Processes to sample from probability distributions. More specifically, I am working on a process called Zig-Zag, which seems to work well for posterior distributions in a Big Data setting. My second supervisor is Dr. Jon Warren. I am very interested in theory and applications of Markov Chains, and more broadly, of Probability Theory.
During my first year I worked with Ellie Archer and Stephen Pidgeon on a research study group on Stochastic Integrable Systems. We were supervised by prof. Nikos Zygouras and dr. Yacine Barhoumi-Andréani.
