I hold a PhD in Political Science from Stanford University. My research sits at the intersection of political economy and comparative politics and studies how elections shape representation. In particular, I examine how electoral rules and institutions affect political careers, party organization and voter behaviour. To study these questions, I apply and extend computational and causal inference methods to newly collected data on elections and local governments across Europe.

My work has been published in the Journal of Politics and Science Advances. I work(ed) with Gary Cox, Jens Hainmueller, Andy Hall, and Andy Eggers. During my time at Stanford, I was also a Graduate Student Affiliate at the Democracy and Polarization Lab and repeatedly served as TA for classes in quantitative methodology and comparative politics.

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

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