Jill Sheppard's research focuses on why people participate in politics, what opinions they hold and why, and how both are shaped by political institutions and systems. Her current projects include studies of ethnic political participation in Australia, opinion formation and electoral behaviour, compulsory voting and its effects on voters, and social class in Australia. Recent papers on participation and voting have been published in Australia and internationally.
Methodologically, her interests focus on sampling and fielding population-based surveys, questionnaire design, and respondent recruitment and retention. Jill is an investigator on Australia's contribution to the Asian Barometer and World Values Survey projects, and the Australian Election Study, as well as authoring the ANUpoll.
