Research

Before founding Volograms, I was a Postdoctoral Research Fellow at V-SENSE, Trinity College Dublin, where I was advised by Prof. Aljosa Smolic. I did my PhD at GTI, Universidad Politécnica de Madrid, under the supervision of Prof. Francisco Morán.

My research interests are computer vision, 3D reconstruction, volumetric video and image processing. I’m especially interested in the reconstruction of the shape an appearance of human models. Representative papers are highlighted.
