Green received her PhD from
Nuffield College, Oxford. She then joined the faculty at the
University of Manchester, before moving to the University of Oxford. In 2017, Green coauthored the book
The Politics of Competence: Parties, Public Opinion and Voters with political scientist Will Jennings. In
The Politics of Competence, Green and Jennings study how voters evaluate the competence of political parties on specific issues. They use data from the United Kingdom, the United States, Canada, Australia, and Germany to study three components of party issue competence: the reputation of parties on particular issues, voters' evaluations of parties on a particular issue, and how well voters think a party is performing overall. Green has served on the editorial boards of prominent political science journals including
Comparative Political Studies and
Political Science Research and Methods. She has been the co-director of the British Election Study, and she was a member of the inquiry established by the
British Polling Council and the
Market Research Society into the failings of the polling relating to the British 2015 general election. She has also done political analysis on
BBC television and radio programs. She received the Research Communicator of the Year award from the
Political Studies Association. In 2018, she was elected a
Fellow of the Academy of Social Sciences. ==Selected works==
