About
I am a doctoral research fellow at the Digitial Signal Processing and Image Analysis (DSB) group at University of Oslo, Norway. My research focuses on enhancing the stability and effectiveness of self-supervised learning (SSL) methods for visual data, under the supervision of Prof. Adín Ramírez Rivera and Prof. Michael Kampffmeyer.
