[CV] [Google scholar]



Hi, I am a senior lecturer in economics at Queen's University Belfast, doing research on market design.

I have published in Games and Economic Behavior, the Journal of Mathematical Economics, Social Choice and Welfare, Economics Letters and Mathematical Social Sciences. My research has been covered by The Economist, the Financial Times, the MIT Technology Review, BBC's Thinking Allowed and Forbes.  

I obtained my PhD from the University of Glasgow in 2017 under the supervision of Hervé Moulin.

I am/have been on the program committee for the 2023, 2024 & 2025 Conference on Economics and Computation, the 2022 & 2024 Matching in Practice Workshop,  and the 2024 Royal Economic Society Conference.

I am co-chairing the Irish Network on Economic Theory. We aim to regularly organize workshops and special sessions at the IEA congress. Get in touch if you want to join!
