What we study
The Ezzeddine Lab studies stars and galaxies to understand how elements formed and evolved in the early Milky Way. They use high-precision spectroscopy and computational models to analyze chemical signatures in stars.

Current projects
First stars and Supernova explosions
Investigating the geometry of supernova explosions from the first stars.
Origin of the r-process
Studies where the r-process comes from, the rapid neutron capture that makes heavy elements, by observing old stars.
