Biography

Professor Andrew Turpin is Deputy Head (Engagement) School of Computing and Information Systems at the University of Melbourne.

I enjoy applying theoretical computer science research in algorithms and data structures to real world problems across many domains. The common thread across my projects in health, political science, data analytics and information retrieval is speed: I like algoritmics and making code that runs fast (and accurately!). This often involves working with large data sets, which requires custom software for processing, and specialised tasks that require novel algorithms (like visual field testing).
I work with companies in Australia, Germany, Italy, Switzerland, USA on computation problems in glaucoma assessment.
