Professor Justin Zobel is a Redmond Barry Distinguished Professor in the School of Computing and Information Systems and Pro Vice-Chancellor (Graduate and International Research). He received his PhD from the University of Melbourne and, prior to returning to Melbourne in 2008, worked at RMIT and NICTA. Prof Zobel is an associate editor of the International Journal of Information Retrieval and in 2008-9 was President of the CORE association of Australasian Departments & Schools of Computer Science. In the research community, he is best known for his role in the development of algorithms for efficient text retrieval. He is the author of "Writing for Computer Science", third edition, and co-author of "How to Write a Better Thesis", third edition and "How to Write a First Minor Thesis". His interests include search, fundamental data structures, and research methods.
