The majority of my work revolves around the area of recovering a dense representation of shape from 2D images. For example, given an image of face, we aim to recover a 3D mesh that best approximates the face that created the image.

I have also been working on parametric image alignment and visual deformable models. If you are interested in this, I suggest you check out a project from my team called Menpo. Menpo is a Python framework for building fitting deformable models, focusing on easy visualisation and data ingestion.
