PhD Candidate in Computer Graphics

GILab | UZ

I’m a first-year PhD candidate in Computer Graphics at the Graphics & Imaging Lab (Universidad de Zaragoza, Spain), under the supervision of Prof. Ana Serrano and Prof. Diego Gutierrez. I have a BSc degree in Computer Science from Universidad de Zaragoza. I obtained my MSc degree in Applied and Theorical Mathematics at Universidad Politécnica de Valencia. My research topics are visual appearance, material perception and deep learning, but I’m open to explore other related fields such as computer vision.
