Ph.D., Information Science, City University (London, UK), 1992

Professor Efthimiadis' expertise is in the area of user-centered design and evaluation of information retrieval systems. His research focuses on the design of front-end interfaces that improve access to databases, and on the evaluation of information retrieval systems. He is interested in the application of probabilistic techniques to information retrieval and in methods that incorporate user preferences and user interaction in the retrieval techniques. Efthimiadis' research in the area of query expansion is concerned with the evaluation of ranking algorithms and the study of the searching behavior of end-users. He is also interested in domain-specific applications of information retrieval, such as medical informatics and economics informatics.

Efthimis was the conference chair of the 29th Annual International ACM SIGIR Conference on Research & Development on Information Retrieval, Seattle, (SIGIR 2006).

Professor Efthimiadis teaches courses on the principles of information retrieval, database design, online search techniques, internet access, introduction to information science, business information and medical informatics.
