Omar Sharif (ওমর শরিফ)

I am a PhD student in the Department of Computer Science at Dartmouth, advised by Professor Nikhil Singh. I also frequently collaborate with Professor Souroush Vosoughi. My research spans Natural Language Processing, Multimodality, and Computational Health. Currently, I focus transforming complex information accessible, interpretable, and actionable representations to improve decision making in high-stake domains like healthcare. To this end, I develop methods to extract structured information from unstructured data [1–3] 1Improving Information Extraction with Learned QueriesEMNLP 2026 Findings 2Explicit, Implicit, and Scattered: Revisiting Event ExtractionEMNLP 2024 3Characterizing Information Seeking Events in Health-Related Social DiscourseAAAI 2024 , design reliable evaluation frameworks for generative models [4–5] 4REGen: A Reliable Evaluation Framework for Generative Event Argument ExtractionEMNLP 2025 Findings 5Document-Level Event-Argument Data Augmentation for Challenging Role TypesACL 2025 , and improving models reasoning across modalities [6–8] 6Disentangling Perception and Reasoning in Multimodal LLMs via Reward DesignAACL-IJCNLP 2026 Findings 7Deciphering Hate: Identifying Hateful Memes and Their TargetsACL 2024 8Align before Attend: Aligning Visual and Textual FeaturesEACL 2024 SRW .
