I am a Senior Research Fellow in the Department of Economics at the University of Oxford, and affiliated with Lady Margaret Hall, Nuffield College, and IZA. I am an applied microeconomist working at the intersection of labour, public, and health economics. I am on the 2025-26 academic job market.

My research agenda has two strands. First, I study the parent-child relationship across three phases: the effects of childbirth, intergenerational dynamics across the life course, and the consequences when the relationship ends at parental death. Second, I examine how policy, identity, skills, and digitalisation shape inequality in economic outcomes as well as in wellbeing more broadly.

My work has appeared in AEJ: Applied Economics, Journal of Public Economics, and AEA Papers and Proceedings, among others. I have several papers under revise-and-resubmit, including two at the American Economic Review. Since 2021, I have attracted and managed about £950k in research funding to Oxford, including an ESRC New Investigator grant (2025-2028).

I communicate research to broader audiences through policy briefs (e.g., VoxEU; IZA World of Labor) and direct engagement with business and policymakers (e.g., via OUBEP). My work has been featured in international media, including the New York Times and The Observer/Guardian.

In my job market paper, Intergenerational Mobility by Sexuality, we develop a population-scale approach to studying sexual minorities in administrative data, providing novel population-level evidence on intergenerational dynamics for a group rarely observable in data sources linked across generations.
