Derek Pun is a M.Sc. student at Simon Fraser University in GrUVi & 3DLG lab, where I have the privilege of working with Prof. Manolis Savva.

Prior to SFU, I received my M.Sc. in Immersive Technologies (VR & AR) from the University of Bristol in 2023, and a B.Sc. degree in AI & Computer Science from the University of Sheffield in 2022.
