I’m an Assistant Professor at the School of Politics and International Relations at the University of Nottingham (2016-present). My research interests include human rights, foreign direct investment, corruption and slavery.
I’m involved in a number of initiatives to promote research transparency. I’m an ambassador at the Center for Open Science (COS) and a catalyst at the Berkeley Initiative for Transparency in the Social Sciences (BITSS).
Before working at Nottingham, I taught statistics for social scientists at the Social Sciences Research Methods Centre, University of Cambridge (2014- 2016). To integrate replication practice into teaching at Cambridge, I developed the Cambridge Replication Workshop. In 8 weeks, graduate students replicated a paper and subsequently published it.
I completed my PhD in Politics and International Studies at the Department of Politics and International Studies at Cambridge in 2014.
Why I started this blog
I started my blog in January 2013 because I was frustrated with the state of reproducibility in the social sciences:
- many journals did not have replication policies
- many authors did not keep replication data files on their computers to send them out on request
- many authors did not keep clearly commented R code or STATA .do files for replication purposes
- some refused to send the data upon request
My wish list
I would like to see the following changes in the social sciences:
- All journals should require that authors upload the data sets and software code for all models used upon acceptance of their article.
- Authors should keep detailed records about data sets, models, R code and .do files for all results presented in the full text, footnotes and appendix.
- Authors should not just ‘promise’ to send data ‘on request’, but do so.
- There should be an open source Journal of Social Science Replication to boost replications not only for learning purposes but also as a valuable contribution to the field.
