Jingtan Wang

PhD student, National University of Singapore

I am a PhD student at National University of Singapore, advised by Prof. Bryan Low, Dr. Chuan-Sheng Foo, Dr. Nancy Chen, and Dr. Zhengyuan. My research is supported by the A*STAR Computing and Information Science (ACIS) Scholarship. I was fortunate to intern with Apple's Video Engineering team in San Diego, where I worked under Manjot Singh Bilkhu. My research interests lie in data-centric language modeling and agentic post-training.
