Research Interests

I have a broad background and research experience in computer vision, medical image analysis and bioinformatics. I was working on medical image segmentation and low-rank modeling for image analysis during my PhD study. After moving to the GRASP Lab at University of Pennsylvania, my primary research interest is 3D object recognition including detection, shape reconstruction and pose estimation. I’m also working on a project on vision-based navigation of UAVs.
