Chia Yu Hung
I am currently a 1st year PhD student at Nanyang Technological University (NTU), fortunately to be advised Prof. Soujanya Poria. My research interest lies in MultiModals and Vision Language Action Models.
Previously, I earned my Bachelor’s degree in Computer Science from Singapore University of Technology and Design (SUTD) in May 2024. Throughout my undergraduate period, I was fortunate to have opportunity to conduct research under Prof. Roy Ka-Wei Lee and Prof. Soujanya Poria.
Current works: I am working on reinforcement learning with action conditioned world models!! Feel free to email me to chat about this!
