Academically, Joy holds a BA (Hons) in Communication (First Class Honours) from Sunway University (Lancaster University), and previously graduated with Distinction in Broadcast Media from LASALLE College of the Arts. Her academic work informs her professional practice, particularly in areas such as gamification, digital communities, and media systems.
