About me

I am currently working at Harvard University as a postdoctoral fellow with Dr. Hanspeter Pfister in the visual computing group. I obtained my Ph.D in Computer Science at Brown University in 2012. At Brown I worked with Dr. Michael J. Black and Dr. Erik B. Sudderth, on Computer Vision and Machine Learning. I am particularly interested in optical flow estimation, motion segmentation, layered model, and motion-based video enhancement.

For updates, please see my webpage at Harvard.
