Fan Nie

I am a first year M.S. student at Stanford University, advised by Prof. James Zou. I am also fortunate to work closely with Prof. Alexandre Alahi, Prof. Percy Liang, Prof. Huaxiu Yao and Prof. Linjun Zhang. Previously, I received my B.S. degree in Computer Science (IEEE Honor Class) from Shanghai Jiao Tong University, where I fortunately worked with Prof. Junchi Yan and Prof. Hang Zhao.

If you are interested in connecting with me, please feel free to reach out.

Research

I am broadly interested in various research topics including reliable AI, foundation models, reinforcement learning and novel evaluation strategies.

My current work focuses on training LLM/MLLM agents through reinforcement learning to enhance their capabilities and reliability.

Miscellaneous

I love the arts, such as the piano, drawing, singing and ikebana. Art and poetry enrich my life, bringing enlightenment amidst the busyness and ordinariness of everyday existence.

My favorite movie is Atonement. Jorge Luis Borges is my beloved poet.

I also enjoy yoga, especially Pilates. If you like Pilates too, we can do it together.
