The Chinese University of Hong Kong, Shenzhen (CUHK-SZ)
My current research focuses on Medical Multimodal Large Language Models (MLLMs), with particular applications in forensic medicine and biosignal analysis (e.g., ECG/EEG), under the supervision of Prof. Wang Benyou. During my undergraduate studies, I was honored to be admitted as a visiting student in the Cenbrain Lab at Westlake University, where I worked under the supervision of Prof. Mohamed Sawan. I am also an active contributor to the open-source community, with pull requests to renowned projects such as Areal. My bachelor's thesis was supervised by Dr. Goh Sim Kuan.
I am currently seeking PhD/Intern opportunities. Feel free to drop me an email.

WaveMind: Towards a Generalist EEG Chat Model Aligned to Textual and Visual Modalities
Ziyi Zeng, Zhenyang Cai, Yixi Cai, Xidong Wang, Junying Chen, Rongsheng Wang, Siqi Cai, Haizhou Li, Benyou Wang
Preprint 2024
This study proposes unifying EEG signals and their paired modalities into a shared semantic space to resolve modality mismatch. It introduces WaveMind-Instruct-338k, the first cross-task instruction-tuning EEG dataset, enabling conversational EEG interpretation. The resulting MLLM achieves strong classification performance and supports open-ended dialogue across tasks.

Specific Endophenotypes in EEG Microstates for Methamphetamine Use Disorder
Xurong Gao, Yun-Hsuan Chen, Ziyi Zeng, Wenyao Zheng, Cheng PengChai, Hemmings Wu, Zhoule Zhu, Jie Yang, Lihua Zhong, Hua Shen, Mohamad Sawan
Frontiers in Psychiatry 2024 Accepted
This study applied EEG microstate features classification within EEG across frequency bands and tasks to classify methamphetamine use disorder (MUD) versus controls. The main conclusion involves MUD endophenotyping, pinpointing alpha-band microstate A as a key biomarker.

Repetitive TMS-based Identification of Methamphetamine-Dependent Individuals Using EEG Spectra
Ziyi Zeng, Yun-Hsuan Chen, Xurong Gao, Wenyao Zheng, Hemmings Wu, Zhoule Zhu, Jie Yang, Lihua Zhong, Weiwei Cheng, Mohamad Sawan
IEEE Sensors 2024 Accepted
This study uses EEG-based relative band power (RBP) analysis and random forest classification to assess treatment effects in Methamphetamine use disorders (MUD) patients. Gamma RBP was found to be a potential biomarker for rTMS efficacy and a candidate signal for closed-loop neuromodulation in MUD.
