Profile

I am a Postdoctoral Research Fellow working on the EU-funded CONSTRAIN project (https://constrain-eu.org). In this project I am looking into large-ensemble climate model simulations in order to identify the role of ocean variability projecting onto historical and future global-mean temperature trends as well separating out the contribution of internal (stochastic) variability, with the overall aim of constraining uncertainty in these trends.

Prior to this, I briefly worked on the NERC-funded SISLAC project with Professor Martyn Chipperfield dealing mostly with analysing recent (post 2000) ozone trends in the lower stratosphere where models and satellite observations exhibit significant discrepancies.

In 2020, I completed my PhD at the Institute for Climate and Atmospheric Science, School of Earth and Environment, University of Leeds working under the supervision of Dr Amanda Maycock and Professor Martyn Chipperield. In my thesis titled as “Modelling the stratospheric residual circulation under historical and future climates”, I dealt with the advective part of the global Brewer-Dobson circulation (BDC) which cannot be directly measured and is relatively poorly constrained in both observations and models. I was able to address several topics related to the representation of the stratospheric residual circulation in models which ultimately progressed our understanding pertaining to mechanistic and diagnostic processes related to the stratospheric residual circulation in numerical simulations.

Before coming to Leeds, I did both my BSc and MSc at the Physics Department, Aristotle University of Thessaloniki (AUTH) pursuing a specialisation in Atmospheric Physics dealing mostly with global climate modelling, chemistry-climate interactions as well as radiative transfer.
