Rolandos Alexandros Potamias
I’m a Research Associate at Imperial College London in 3D Computer Vision and Deep Generative Models in non-Euclidean Spaces. I’m also a Senior Research Scientist at Huawei Noah's Ark, working with Jiankang Deng. My current interests lie in the intersection of generative models and 3D avatars, with particular emphasis on 3D Hands, Faces and Bodies. Previously I received my PhD in 3D Computer Vision from Imperial College London advised by Stefanos Zafeiriou. Prior to my PhD, I received my MEng degree at the National Technical University of Athens, where I was supervised by Prof. Andreas Stafylopatis.
