Mohammad Aliannejadi

Mohammad Aliannejadi is an Assistant Professor at the Information Retrieval Lab (IRLab) within the Informatics Institute at the University of Amsterdam. His research focuses on conversational search systems, information retrieval, and recommender systems, with an increasing emphasis on Large Language Model applications in IR. He obtained his PhD from the Faculty of Informatics at Università della Svizzera italiana (USI) in Lugano, Switzerland, and completed his MSc at Tehran Polytechnic in Iran.

His research interests span conversational search systems, clarification question generation, mobile search, cross-market recommendation, and point-of-interest recommendation. Dr. Aliannejadi has made significant contributions to understanding how users formulate information needs in conversational settings and how systems can effectively respond through clarification mechanisms. His work bridges theoretical IR concepts with practical implementations, particularly in mobile contexts where information needs often evolve rapidly.

His recent publications show a clear trend toward leveraging Large Language Models for conversational search evaluation, query understanding, and performance prediction. The 15 most recent articles demonstrate his leadership in adapting traditional IR techniques to the LLM era, with particular focus on efficient and effective conversational search systems that can handle complex user information needs through natural dialogue.

Dr. Aliannejadi is deeply embedded in the IR community through extensive service activities. He has served as Program Co-Chair for ICTIR 2023, Tutorial Co-chair for ECIR 2024, and Lab Co-Chair for CLEF 2023. He regularly organizes workshops such as XMRec, SCAI, and MICROS, and has been a SIGIR Student Liaison. His service extends to program committees for major conferences including SIGIR, ACL, WSDM, and ECIR, and as a reviewer for journals like TOIS and TKDE.

His leadership extends to organizing significant academic events including the 15th European Summer School in Information Retrieval (ESSIR 2024) and serving on the Program Committee for the Bachelor Program in AI at UvA. His lab, IRLab (formerly ILPS), focuses on developing innovative approaches to information access through conversational interfaces and advanced retrieval techniques.
