Rohan Alexander is an Assistant Professor in the Faculty of Information and the Department of Statistical Sciences. Prior to joining the Faculty of Information, he completed a PhD at the Australian National University, started a business, and worked at the Australian central bank. His research interests tend to fall into one of three tranches: workflow analysis, text-as-data, and multilevel regression with post-stratification.
Rohan’s background and research are multidisciplinary but fall broadly in the realm of using data science approaches to explore questions in economics, history, and politics. Rohan’s research typically involves first constructing new datasets from historical and other sources in a reproducible way, drawing on methods of digitization, record matching, survey collection, and web scraping. After constructing datasets, Rohan then typically uses quantitative methods to analyse the large amounts of information contained in them, drawing on techniques from text analysis, statistical learning, and Bayesian methods, as appropriate. As Rohan’s work is focused on individuals, issues of privacy and consent are of critical importance, and inform all aspects of his research. Additionally, he contributes to open science best practises to ensure both reproducibility and replicability.
