Abdelrahman Abdallah

Pronouns: He/Him

Hello. I’m Abdelrahman Abdallah, a Ph.D. graduate in Computer Science advised by Professor Adam Jatowt at the Digital Science Center (DiSC), Department of Computer Science, University of Innsbruck. I graduated with honors in September 2026, receiving Sehr gut (1), the highest grade in the Austrian grading system. Currently, I am a research assistant at DiSC. Previously, I worked as a machine learning engineer at DISCO App in Cairo and at KMG Engineering in Kazakhstan, as a machine learning researcher at Satbayev University and Università Ca’ Foscari Venezia, and as a research and teaching assistant at Assiut University in Egypt.

As a researcher in machine learning (ML) and natural language processing (NLP), my work focuses on large language models (LLMs), information retrieval, and question answering. I am particularly interested in how LLMs can be used for document retrieval and reranking, robust QA on noisy or OCR text, and reasoning over temporal information in dynamic collections.

My research interests include:

• Reasoning-Intensive Information Retrieval & Reranking
• Efficient & Multimodal Retrieval Models
• Temporal Information Retrieval & Question Answering
• Retrieval-Augmented Generation & Agentic Search
• LLM Evaluation, Calibration & Bias Mitigation
