The main themes of my research are poverty, inequality and income distribution divided into three strands: the meaning and measurement of poverty and inequality, including statistical analyses of welfare distributions in developing and developed countries; the analysis of the causes of poverty and inequality, and the analysis of relationships between poverty and migration. 

Past research includes  trade reform and poverty dynamics in Zambia, China and Vietnam; an analysis of Inequality in Latin America; the relationship between conflict and poverty with the MICROCON research centre; work with SCMR on migration and poverty in Albania and Ghana. Beween 2009 and 2013 I was on secondment to DFID as Senior Research Fellow working in the Growth Research Team on agriculture and conflict.

I am currently Theme Leader with Sussex's Migrating Out of Poverty Research Centre, funded by DFID, with projects running in Ghana, Zimbabwe, Ethiopia, Bangladesh, Indoneisa and Myanmar.

I have supervised over 20 PhD students at Sussex and I currently supervise PhD students in both Economics and International Development on topics spanning poverty, inequality, migration, conflict, rural and agricultural development in numerous countries including Brazil, Chile, Mexico,  Venezuela, Ghana, Ethiopia, Zambia, India, Cambodia and Vietnam.
