Natural language processing & multimodal learning

Mohammadmostafa Rostamkhani

Portrait of Mohammadmostafa Rostamkhani

I study how language and vision-language models reason and respond to challenging inputs. My work spans visual illusions, multilingual NLP, and model evaluation. I hold an M.Sc. in Artificial Intelligence from IUST and currently work as an NLP Researcher at ZharfaTech.

Academic background

My research interests sit at the intersection of language, vision, and reasoning. I have worked on benchmarks for multimodal perception, multilingual claim retrieval, puzzle reasoning, and hate speech detection.
