I am a final year Ph.D. candidate at UT-Arlington, with a Master's degree from Shanghai Jiao Tong University and a Bachelor's degree from Northwestern Polytechnical University. My research focuses on the intersection of brain networks and deep learning research, with an emphasis on brain-inspired AI and information theory-based AI. My work is applied to (medical) image processing, with major contributions to human brain network analysis, image classification, domain adaptation/generalization, and semi-supervised learning.

I will be on the job market, seeking full-time positions as a research scientist/engineer or Postdoc, among other roles. Please feel free to reach out if interested in my work.

Projects

NoisyNN: Exploring the Impact of Information Entropy Change in Learning Systems (Individual Project)

Triggered by the impressive performance improvement achieved through the addition of noise, I delve deep into the mechanism explaining why adding noise would work by proposing a new learning theory. In this context, I consider additional information beyond the image itself as noise, with the application of this theory being NoisyNN.

Free Water in White Matter Hyperintensity (Collaborate with MSU and UT Southwestern)

We proposed a data processing framework to assess FW distributions in WMH and normal-appearing WM as well as in different WM fiber tracts.

Longitudinal Functional Connectivity Prediction (Collaborate with UNC)

We proposed a conditional intensive triplet network (CITN) for longitudinal prediction of the dynamic development of infant FC, which can traverse FCs within a long duration and predict the target FC at any specific age during infancy.

Disentangling Brain Networks using Twin-Transformer (Collaborate with UGA)

We proposed a Twin-Transformers framework to simultaneously infer common and individual functional networks in both spatial and temporal space, in a self-supervised manner.

Exploring core-periphery relationship between Gyri and Sulci (Collaborate with UGA)

We designed a novel Twin-Transformer framework to explore and unveil the unique functional roles of gyri and sulci as well as their relationship and interaction in the whole brain function.

Instill Core-Periphery Principle into Transformers (Work with UGA)

This work provides novel insights for brain-inspired AI: we can instill the efficient information communication mechanism of BNNs into ANNs by infusing similar organizational principles of BNNs into ANNs.

Hobbies

Roadtrip, Hiking, Tennis.

Step into nature is one of my favorite activities during my leisure time. I enjoy going hiking in randomly selected national parks with Pet friends.
