My Twitter Profile

I am a Senior Data Scientist at Deliveroo, using state-of-the-art causal inference and statistical methods to support business decisions, product rollouts and improve consumer decisions. Previously, I worked as an Applied Intern at Uber. I specialise in estimating treatment effects and other metrics in experiments and developing alternative models where straightforward A/B experimentation is not possible.

I hold a PhD in Political Science from Stanford University. In my research, I am broadly interested in the political economy of elections. In particular, my research investigates how electoral institutions shape legislative behaviour, political party organisation, and accountability towards voters. To that end, I use and develop new quantitative and causal inference methods. I work(ed) with Gary Cox, Jens Hainmueller, Andy Hall, and Andy Eggers. I am also a Graduate Student Affiliate at the Democracy and Polarization Lab.

Prior to coming to Stanford, I was a DPhil Student at Oxford University (Nuffield College). I hold a BA in Philosophy, Politics, and Economics (PPE) from Warwick University, and a MSc in Politics Research from Oxford University (St. Cross College).
