Foivos Paraperas Papantoniou

Hi! I am a PhD student at the Department of Computing, Imperial College London, advised by Prof. Stefanos Zafeiriou. My research interests revolve around Computer Vision and Machine Learning, with a focus on 3D reconstruction, photo-realistic rendering and editing of human faces with generative models. Currently, I am also working as a research intern at Huawei Technologies R&D, UK. Prior to starting my PhD, I did my undergraduate studies at the National Technical University of Athens, where I was supervised by Prof. Petros Maragos and Dr. Anastasios Roussos during my thesis.
