My friends call me Nikos, and I work as a research scientist at Meta Reality Labs focusing on 3D generative models with applications to virtual humans. In the past I've worked on 3D reconstruction, dense correspondences and neural rendering. I obtained my Ph.D. from the University of Houston where I worked on 3D human pose estimation, visual attributes and text-to-image retrieval. I currently serve as a mentor at Deep Learning Indaba.
