Hello! 👋
I’m a Ph.D. candidate in Computer Science at Wayne State University, specializing in Computer Vision and Image Segmentation. As part of the Trustworthy AI Lab under Dr. Dongxiao Zhu, my research focuses on leveraging Vision-Language Models to enhance segmentation in Medical Imaging and Remote Sensing.
Currently, I’m a Graduate Research Assistant (GRA) in the Computer Science Department, where I explore AI-driven solutions for real-world challenges in trustworthy and interpretable machine learning.
Always open to collaboration and discussions—feel free to connect! 🚀

Research

Current Research

I specialize in Computer Vision, specifically focusing on Image Segmentation. My expertise lies in two main areas: Bio-Medical Image Segmentation and Geographical Image Segmentation.
In the field of medical image segmentation, our objective is to accurately identify and segment tumors within different organs of the body, using various imaging modalities such as CT scans, MRI scans, and others.
Regarding geographical image segmentation, our goal is to develop a pedestrian network capable of segmenting different pedestrian objects, including roadways, sidewalks, crosswalks, and curb ramps. This task is crucial for applications involving satellite/ aerial imagery. Our recent work on this area can be found here: "GeoSAM: Fine-tuning SAM with Sparse and Dense Visual Prompting for Automated Segmentation of Mobility Infrastructure",
Additionally, I also engage in algorithm optimization techniques as part of my work.
