#Senior Research Scientist at OPPO

Currently, I am working on machine learning and signal processing for wearable health applications, with a focus on blood pressure estimation and hypertension-related risk screening from wrist PPG signals.

Ph.D. at the iVPL lab at Northwestern University, supervised by Prof. Aggelos Katsaggelos and Prof. Daniel Kim. My research focuses on deep learning and computer vision -based classification, detection, segmentation, and generation in manufacturing and medical imaging.

My first two years were spent studying automatic defect detection and thermal prediction during additive manufacturing; then, I worked on segmentation and unsupervised domain adaptation in MRI, CT, OCT, X-ray, etc. I am proficient in RNN, GRU, GNN, GAN, Transformer, etc.

Previously, I obtained a master’s degree in Mechanical Engineering from Huazhong University of Science and Technology (HUST) in 2019, supervised by Prof. Bin Li and Prof. Xinggang Wang. I received a Bachelor’s degree in Materials Processing and Control Engineering from Qiming College, HUST, in 2016.
