I am a Senior Research Fellow in the School of Computing at the National University of Singapore, where I work with Angela Yao. Before NUS, I was fortunate to spend a year at the Australian National University during my Ph.D., working with Salman Khan and Fatih Porikli.
My research aims to make machines understand complex, multi-step human activities from long videos. I am broadly interested in procedural activity understanding and data-efficient video learning, with a longer-term goal of building vision-based assistants for real-world tasks.
I maintain two community resource lists, Awesome-PAU and Awesome-TAS.
Open to collaboration. If you are working on video understanding, procedural or egocentric activity, or AI assistants for real-world tasks, and would like to collaborate, please get in touch at dinggd [at] comp.nus.edu.sg.
