About me

I am a master's student in Health Data Science at Juntendo University, working in the Himeno-Sun Lab under the supervision of Prof. Ryutaro Himeno and Prof. Zhe Sun at Juntendo, and Dr. Chao Li at RIKEN AIP.

As part of the Brain/MINDS 2.0 Digital Brain Project, I adapt Transformer-based sequence models to rat neural recordings and ask how well what they learn carries over across trials, recording sessions and animals. I am interested in neural population dynamics and coding, and in computational models of cognition and behavior.

Before Juntendo, I received a BSc (Hons) in Information and Computing Science from Xi'an Jiaotong-Liverpool University, a dual degree with the University of Liverpool.

Projects

A VR fitness game about fishing

Team project, Unity, 2023-2024

A VR game where you play as a cat catching fish through physical exercise in a world without humans.

Role: I came up with the concept, designed the gameplay, wrote most of the Unity prototype, and led the final team presentation.

NLP for production safety

Undergraduate dissertation, 2023–2024

An undergraduate project exploring the use of BERT to classify risk levels and extract information from industrial safety records.

Role: I experimented with several language models using limited, inconsistently formatted data. The project remained a proof-of-concept prototype rather than a finished application.
