Jue-mode Music Intervention for ICU Delirium

First Hospital Of Qinhuangdao, Research Coordinator & Co-Author

Location: Qinhuangdao, China

Advisor: Qiujian Xu

Period: 2025 – present

Randomized trial on ICU delirium intervention using Jue-mode music. As corresponding author and research coordinator, organized patient flow logistics, oversaw ICU data collection, enforced rigorous de-identification and quality assurance, and supported signal analysis. Operates at the intersection of cognitive science, sound perception, arousal modulation, and behavioral measurement.

Real-Time Audio Visualization Permalink

A real-time audio visualization project featuring a full GUI control panel and a preset system, with support for local audio uploads and system audio input.

Real-Time Multimodal Digital Human Permalink

Built a real-time multimodal digital human for dialogue and music using full-stack development. The system ingests text, audio and video in real time, uses face recognition to personalize responses and manage attention, and matches lip and facial movements to generated speech. The music agent tracks emotional state from voice and image, logs these states for experiments, and queries a backend database to select tracks that match the user's emotion and request. Implemented the web frontend in JavaScript, and the system is now in production at a provincial court.

Real-Time Digital Human Dialogue System

Deployed in China Post Group,Heilongjiang Provincial People's Court

Location: China

Period: 2025 – present

Architected and executed a modular, ultra-low-latency pipeline for avatar rendering and full-duplex A/V via WebRTC, implementing an asyncio-based streaming stack that reliably sustains 30 fps video and 16 kHz audio for a tight perception-action loop. The system has been demonstrated and deployed at the China Post Group.

AI-Driven Music Therapy System

Deployed in Henan University of Chinese Medicine

Location: China

Period: 2025 – present

As overall technical lead, architected a low-latency, closed-loop Music Therapy system which is deployed at Henan Medical University, Peking University International Hospital, and the Heilongjiang Provincial People’s Court. It streams high-fidelity EEG and audio, performs robust artifact rejection and feature extraction, and fuses neural and acoustic signals with a Transformer to drive a moment-to-moment generative music controller. Added 30 fps facial-affect estimation and voice-prosody analysis, then designed reliability-aware multimodal fusion so the controller adapts in real time and quantifies therapeutic response.

Harnessing Auditory Laughter to Enhance Pain Tolerance

Yanshan University, Corresponding author

Location: Qinhuangdao, China

Advisor: Qiujian Xu

Period: 2025 – present

Examining how auditory laughter affects acute pain tolerance, whether parasympathetic activation and emotional contagion drive this effect, and how individual traits (empathy/pain sensitivity) moderate its analgesic benefits. Conducted with 74 participants using Cold Pressor Test with HRV and EDA recording. Manuscript submitted to Journal of Cognitive Neuroscience.
