I am a fourth year PhD student at Leibniz University Hannover, Germany and work as a researcher in the Fake Narratives project. Prior to this, I was a MSCA fellow and worked on one of the projects in CLEOPATRA ITN. I am employed as a research assistant at Visual Analytics Group, TIB and advised by Dr. Ralph Ewerth. I closely collaborate with Dr. Sherzod Hakimov (Now at University of Potsdam), Dr. Eric Müller-Budack and Christian Otto. My current work and research revolves around interdisciplinary topics like deep/machine learning, multimodality with focus on Computer Vision and NLP, semiotics and digital humanities.
My research on multimodality spans across challenging applications like claim, hate-speech, sentiment and out-of-context media detection. My thesis focuses on multimodal alignment, cross-modal relations and semiotics in the context of multimodal media content in the news domain.
