Associate Professor Andrew Trotman is a member of the Department of Computer Science in the School of Computing at the University of Otago. He received a Bachelor’s degree in Computer Science in the 1980s, a Master’s degree in the 1990s, and a PhD in the 2000s. Between his degrees, Trotman worked in commercial roles and as a researcher. His career includes affiliations with eBay, Inc., and Queensland University of Technology. In 2016, he returned to the University of Otago as Associate Professor, where he continues his academic contributions.
Trotman’s research specializations encompass information retrieval, search engines, and software engineering. He investigates efficient methods for finding and extracting useful information from large datasets, as reflected in his query: "Can we find and extract useful information from the gigabytes that are available? If we can then how can we build efficient systems to do this?" He has produced 182 publications, garnering over 2,800 citations. Key recent works include Trotman, A., Tyler, M., McAlister, H., Button, C., & Szymanski, L. (2026). Factors affecting the clarity of nondominant handwriting versus dominant handwriting.
