Biography
My research focuses on the study of galaxies of different morphologies, both in the nearby and distant Universe, and investigating the interplay between stellar populations and cosmic dust. My personal goal is to contribute to the holistic understanding of galaxies, their formation, and evolution.
I hold extensive expertise in software packages like CIGALE and Prospector for spectral energy distribution (SED) fitting, SKIRT for radiative transfer modelling, GALFIT and Statmorph for morphological analysis. My experience in optical, near-, mid-, and far-infrared photometry as well as optical spectroscopy and radio interferometry, makes me quite versatile in the extra-galactic community, as the 'status quo' has shifted towards multi-wavelength synergies.
As a PhD student at the National Observatory of Athens, I investigated the intrinsic properties of galaxies, using advanced radiative transfer and SED fitting techniques. These methods enabled me to quantify how the different stellar populations influence the dust heating processes, a critical component in interpreting multi-wavelength observations.
In 2020, I was awarded a 3-year FWO postdoctoral fellowship at Ghent University. During this time, I have taken an active role in three major international projects: the IMEGIN consortium which is dedicated to the mm study of nearby galaxies, the LEGA-C consortium that has collected spectroscopic data for 4000 galaxies at the distant Universe, and more recently the Euclid consortium. My research contribution in the Local Universe working group in Euclid led to my current postdoctoral position at the University of Liège. There, I got the opportunity to study galaxies from a new, exciting perspective, through strong gravitational lensing. Strong lensing is a powerful tool to study the mass structure and evolution of galaxies and constrain their stellar initial mass function. My background in measuring galaxy properties allows me to bridge the gap between galaxy evolution and gravitational lensing studies.
