Soonbin Lee (이순빈)

I'm a Research Associate at Fraunhofer Heinrich-Hertz-Institut (HHI) in Berlin, Germany. I work in the multimedia communications group, which primarily focuses on immersive media technologies such as NeRF, 6DoF media compression and streaming system.

Before joining the HHI, I received B.S. degree from Gachon University and M.S. degree from Sungkyunkwan University (SKKU). I participated in the standardization of ISO/IEC 23090-12 MPEG immersive video (MIV), with Prof. Eun-Seok Ryu.

Most of my research focuses on processing and transmitting new media. Specifically, I'm interested in visual data compression and video coding systems for multimedia.
