I am a Ph.D student in Computer Science, Boston
University. As a member of Image and Video Computing (IVC) group,
I work with Prof. Margrit Betke. My primary research interests focus on
computer vision, machine learning, combinatorial algorithm, and in particular, I have been working on
object segmentation, detection and tracking. I expect to graduate this summer.

Research
- Infrared Thermal Video Analysis of Wild Animals
- This project is to census wild animals like
Brazilian free-tailed bats for understanding the ecological and economic
impact of these animals on terrestrial ecosystems. Several
interesting problems need to be solved, such as automatic
counting and tracking a large number of objects in infrared thermal videos from single or
multiple cameras; gesture recognition in
spatial-temporal domain; statistical analysis on group behavior;
multiple-sensor fusion, etc.
- Hand Gesture Recognition and Tracking
This project is to segment and track articulated object like human hand with highly cluttered background to assist American Sign Language Recognition. The challenge is to build a robust and near real-time system to recognize hand gesture in uncontrolled environment and handle self-occlusion of fingers in 2D as well.
- Tracking of Cell Populations in Response to Physical Stimuli
This project is to reveal the behavioral response of fibroblast cells to changes in hydrogel conditions. The system has to track unknown number of cells in time-lapse phase-contrast microscopy images, and identify cell division/death as well as morphology deformation under different stimuli.
