Research Interests: His work centers on high-redshift galaxy studies using data from the James Webb Space Telescope (JWST) and the JADES survey. Key areas include:

• Galaxy formation and assembly histories
• Star formation processes at cosmic dawn
• Spectroscopic analysis of distant galaxies
• Chemical evolution and dust formation in early universe

Publication Trends: Joris's research focuses on observational astrophysics at extreme redshifts (z>3), utilizing cutting-edge spectroscopic techniques and JWST data. His recent work examines:

• Quenching mechanisms in early galaxies
• Ionization properties of high-redshift populations
• Gas reservoirs in primeval galaxies
• PAH features and extinction curves at cosmic dawn

Labs & Teams: Joris collaborates with international teams through the JADES project and works within the Cosmic Dawn Center at the Niels Bohr Institute.
