About Me

I am a first-year PhD student in Computer Science at Vanderbilt, supervised by Dr. Yuankai Huo. My current research interest lies on AI for Healthcare, where I am particularly interested in leveraging artificial intelligence to optimize clinical workflows and improve diagnostic accuracy. Before joining Vanderbilt, I received my B.Eng. degree in Biomedical Engineering from Southern University of Science and Technology (SUSTech) in 2026. At SUSTech, I worked in the Contactless Healthcare Lab under the supervision of Dr. Wenjin Wang, focusing on the applications of remote photoplethysmography (rPPG). Outside of research, I enjoy playing badminton and am trying tennis.

Projects

Sleep Staging

Contactless Smart Infant Sleep Monitoring System

Developed a multispectral physiological imaging system for precise, contactless monitoring of infant vital signs, in collaboration with a leading hospital in Wenzhou. Established an interpretable video-based sleep/wake classification model to enhance monitoring accuracy from consumer-grade to clinical-grade standards. Leveraged ECG and PPG signals to extract and validate infant motion metrics for preliminary sleep analysis. Deployed open-source human pose estimation and optical flow algorithms to compute key-point motion features, confirming feasibility of camera-based polysomnography (PSG) for infant sleep staging. Conducted camera-based PSG monitoring on 100 infants to establish normative sleep-stage benchmarks. Extracted limb movement coordination and intensity features from video data, applying SVM and Random Forest classifiers for binary and multi-class sleep-stage classification. Applied DL algorithms (LSTM, Transformer) to improve the accuracy of infant sleep stage classification.

BCI

SSVEP-based BCI Robotic Car Control System with MATLAB

Collected EEG signals from occipital regions using gold cup electrodes and a Cyton board (250 Hz). Applied Butterworth filters for noise reduction and extracted key EEG components (4–35 Hz). Implemented and compared CCA and FFT methods to decode SSVEP frequencies with high accuracy. Transmitted motion commands via Bluetooth to demonstrate reliable and precise human-machine interaction.

ECG

MATLAB-based ECG Signal Acquisition and Processing

Developed a user-friendly prototype for heart health monitoring, emphasizing real-time analysis and ease of use. Built a differential circuit and analogue filtering system for accurate ECG signal measurement. Integrated the AD8232 Heart Rate Monitor and MATLAB to process ECG signals via an NI USB 6009 module. Configured a MATLAB GUI for real-time sampling, noise removal, and enhanced waveform analysis.

Seizure

Multidimensional Video-based Contactless Infant Seizure Monitoring

Developed a real-time monitoring and prediction algorithm for infant seizures in collaboration with a a leading tertiary hospital in Guangzhou, aiming to establish a low-cost, contactless detection system to mitigate resource limitations and inconsistencies in seizure diagnosis quality. Preprocessed raw ECG signals to extract heart rate and calculate heart rate variability (HRV). Utilized remote photoplethysmography (rPPG) to extract heart rate and HRV from video data for non-invasive physiological monitoring. Applied optical flow techniques to analyze global and skin-region motion in vEEG videos. Deployed open-source human pose estimation tools to detect infant keypoints and compute motion intensity. Analyzed limb movement intensity using cross-correlation and Pearson correlation coefficients to integrate motion and physiological signals. Introduced a camera-based solution for NICU settings, enabling contactless monitoring of infant motion and vital signs with improved precision and efficiency.

rPPG Demo

Every heartbeat changes the blood flow in the vessels of your face, which slightly changes the intensity of the light reflected by your skin. By capturing these changes with your camera, we calculate your heart rate. This technique is called remote photoplethysmography (rPPG).

The demo runs the rPPG algorithms used in the Contactless Healthcare Lab led by Dr. Wenjin Wang at SUSTech, entirely in your browser. For details, see Algorithmic Principles of Remote PPG (Wang et al., IEEE TBME, 2017).
