Ryoj completed his Bachelor’s degree in Physics in 2026 with cum laude distinction. His undergraduate research focused on investigating the effect of increasing interatomic repulsion on the electronic properties of sapphire with chromium impurities. With particular focus on the crystal field splitting of the Cr 3d orbitals, his work is part of efforts to completely understand the red color of rubies. He is now continuing his MS Physics studies with the support of a UP Teaching Associateship.
