About Me

I now pursue scaling law research at Bytedance Seed, and help our squad scale and interpret foundation LLM/VLMs.

Previously, I completed my PhD in 2023, during which I spent joyful and quality time at Meta FAIR, Amazon AWS AI Lab, Microsoft GenAI, and Google Cloud AI. Grateful to all my mentors and peers. My PhD topics were Medical Computer Vision and 3D Scene Understanding. Before that, I also got my bachelor degree from the University of Sydney in Australia, with a university medal received in computer science.

- I petted an axolotl and Debbie was her name.
- I am was fascinated by lure fishing. It's so chill to cast and chinwag with buddies overnight No Big Fish in Darling Harbor any more just 'NO FISH' (corrected by my mate Junkai: just dont go pls). Nightwind is was too freaking sharp and we are fun were just young and restless and bored.
- I fancy still waters as they generally run deep.
