I am currently a research fellow in the research group of Prof Bruce Fischl at the Martinos Center for Biomedical Imaging, MGH. I work on various registration projects, including surface and volumetric registration of brain MRI images and diffusion tensor image (DTI) alignment. A nice and concise summary of our group's activity is summarized on this PDF poster.
I am also officially affiliated with the Medical Imaging Group at CSAIL, MIT, where I did my PhD.
For more details, see my CV and the list of publications below.
