Short Bio


I am currently a Postdoctoral Researcher at the Idiap Research Institute, supervised by Prof. Daniel Gatica-Perez and Dr. Jean-Marc Odobez. I am also a guest researcher in the Digital Humantities Institute (DHI) at École Polytechnique Féderale de Lausanne (EPFL). Before joining Idiap, I pursued my PhD degree in the Centre for Vision Speech and Signal Processing (CVSSP) at the University of Surrey, supervised by Dr John Collomosse and Dr Krystian Mikolajczyk.
