Dr. Grigorios Chrysos
Biography
I am currently a postdoctoral researcher in Ecole Polytechnique Federale de Lausanne (EPFL). You can find my new site at: https://people.epfl.ch/grigorios.chrysos/?lang=en. A detailed list of publications can be found in my Google Scholar page.
Previously, I was a PhD student in the the Department of Computing, Imperial College London, U.K., working at the iBUG group. I received my diploma (M.Eng.) in Electrical and Computer Engineering from National Technical University of Athens (NTUA), Greece. My main research interests lie in machine learning and computer vision.
