Lecturer in Astrophysics

Research Overview

I conduct a wide range of observations at various wavelengths and use different telescopes (e.g. VLT, Subaru, CFHT, ALMA, INT, WHT) in order to understand how galaxies like our own Milky-Way formed and evolved from the primitive Universe till today. I also look for and study some of the most distant, early galaxies. Most of my research is done by conducting and exploring some of the largest/widest narrow-band surveys ever done, particularly for sources with emission lines. Due to the uniform and self-consistent selection, galaxies found with the narrow-band technique across cosmic time are ideal to understand how the statistical properties of galaxies change accross cosmic time, but also to conduct detailed follow-up studies that can really unveil the physics and nature of distant sources.
