Ms Addison is a consultant researcher and analyst of governance with practical experience in the reconstruction of post-conflict societies and the reform of public administration in states in transition. She has a particular expertise in the methods of computer-assisted qualitative and quantitative text analysis.

Ms Addison earned a Master of Research in Political Science from LSE in 2007 concentrating on public administration, public policy change and quantitative analysis. Her doctoral research at LSE investigates the foundations and determinants of state administrative capacity to implement policy, in particular the direction of the relationship between administrative capacity and economic growth. Ms Addison also holds an MA in international economics and European studies from the Johns Hopkins School of Advanced International Studies, Washington, DC, and a BA in political science from the University of Michigan, Ann Arbor.

As a practitioner, Ms Addison has designed, implemented and evaluated projects to reform social policy and develop institutions and human capacity for governance in Central, Eastern and South-Eastern Europe and in Mongolia.

Her current research, within the research programme of Dr Denisa Kostovicova, uses text analytic methods to investigate deliberation in post-conflict societies.

Her earlier research, with Dr Aude Bicquelet, explored why governments or political parties commit to holding referenda on matters associated with European integration, examining in particular the arguments of legislators for or against the use of referenda. This research was published in Quality and Quantity and Parliamentary Affairs.

Ms Addison’s teaching experience at LSE includes public choice and game theory (2010–2012) and computer-assisted qualitative and quantitative text analysis (2012–2021). In recognition of her contribution to teaching in the Government Department, she was awarded the LSE Teaching and Learning Centre/LSE Student Union Teaching Excellence Award in 2012.
