I am a first-year PhD student in Computer Science at the University College London (UCL), affiliated with Web Intelligence Group (WI) at UCL Centre for Artificial Intelligence (UCL AI Center). I am fortunate to be advised by Prof. Emine Yilmaz and Nick Craswell. I am working on problems at the intersection of Machine Learning and Information Retrieval. My research interests are mainly in recommender systems, bias and fairness, and conversational systems.
Prior to that, I obtained my MSc in Computer Science from University of Zanjan (ZNU), where I was advised by Prof. Mohsen Afsharchi and Dr. Mitra Baratchi (co-supervisor from Leiden University) and worked on context-aware recommender systems. I received my B.Sc. degree from the University of Zanjan.
