He also holds a Bachelor's in Engineering Psychology, and his academic work spans human-centered design, UI/UX, and VR/AR ergonomics. He is particularly passionate about bridging the gap between people and technology — designing systems that feel intuitive, inclusive, human, and also fun. Outside of research, Robin enjoys building things from the ground up — from custom arcade cabinets and ESP32-based hardware projects to game development in Godot. He also loves sports and is a passionate football player.",
