Justin Zobel

Zobel received his Ph.D. in computer science from the University of Melbourne in 1991. His doctoral research was in type theory for logic programming.^[3] Following his Ph.D., he held academic appointments at RMIT University, where he was part of the team that developed an open-source search engines, MG. His work at RMIT contributed to the development of scalable methods for indexing and searching large text collections.^[4]

Zobel later returned to the University of Melbourne, where he was appointed professor and subsequently Redmond Barry Distinguished Professor.^[5] He has served in administrative roles including Head of the School of Computing and Information Systems and currently as Pro Vice-Chancellor for Graduate & International Research.^[6] His has published books Writing for Computer Science^[7] and How to Write a Better Thesis, co-authored with David Evans and Paul Gruba.^[8][9]

Zobel's research has primarily focused on information retrieval, text indexing, search engine architecture, and data compression. He has contributed to the development of efficient, scalable algorithms for managing and searching large-scale textual data. He has collaborated with Alistair Moffat and others on inverted indexes, similarity measures, and compression techniques.^[10][11] He has worked on MG and later Zettair, text retrieval systems designed for high performance on modest hardware.^[12] He has also explored self-indexing, dynamic tries, and burst tries as innovative approaches to managing large string datasets.^[13]
